A basic diagram of the circuit and pin connections is shown in Figure 1. +VS 0.1 F 7 V-IN 2 1 MW 50 kW 50 kW VO = (V+IN - V-IN) 2.7778 kW 6 A1 V+IN 3 1 MW VO 52.6316 kW INA148 4 0.1 F 1 -VS Figure 1. Basic Circuit Connections To achieve its high common-mode voltage range, the INA148 features a precision laser-trimmed thin-film resistor network with a 20:1 input voltage divider ratio. High input voltages are thereby reduced in amplitude, allowing the internal operational amplifier (op amp) to "see" input voltages that are within its linear operating range. A "Tee" network in the op amp feedback network places the amplifier in a gain of 20 V/V, thus restoring the circuit's overall gain to unity (1 V/V). External voltages can be summed into the amplifier's output by using the REF pin, making the differential amplifier a highly versatile design tool. Voltages on the REF pin also influence the INA148's common-mode voltage range. In accordance with good engineering practice for linear integrated circuits, the INA148's power-supply bypass capacitors should be connected as close to pins 4 and 7 as practicable. Ceramic or tantalum types are recommended for use as bypass capacitors. The input impedances are unusually high for a difference amplifier and this should be considered when routing input signal traces on a PC board. Avoid placing digital signal traces near the difference amplifier's input traces to minimize noise pickup. Operating Voltage The INA148 is specified for 15-V and 5-V dual supplies and 5-V single supplies. The INA148 can be operated with single or dual supplies with excellent performance. The INA148 is fully characterized for supply voltages from 1.35 V to 18 V and over temperatures of -40C to 125C. Parameters that vary significantly with operating voltage, load conditions, or temperature are shown in the Typical Characteristics section. Gain Equation An internal on-chip resistor network sets the overall differential gain of the INA148 to precisely 1 V/V. Output is accordance with Equation 1.

The exact input voltage range depends on the amplifier's power-supply voltage and the voltage applied to the REF terminal (pin 1). Typical input voltage ranges at different power supply voltages can be found in the applications circuits section. Offset Trim The INA148 is laser-trimmed for low offset voltage and drift. Most applications require no external offset adjustment. Because a voltage applied to the reference (REF) pin (pin 1) is summed directly into the amplifier's output signal, this technique can be used to null the amplifier's input offset voltage. Figure 2 shows an optional circuit for trimming the offset voltage. +VS 7 2 V-IN 1 MW 50 kW 50 kW VO = (V+IN - V-IN) 2.7778 kW 6 A1 190 W V+IN 3 VO 52.6316 kW 1 MW INA148 4 -VS VREF 1 +15 V 10 kW 10 kW 10 W 15-mV Offset Trim Range, RTI -15 V Figure 2. Optional Offset Trim Circuit To maintain high common-mode rejection (CMR), the source impedance of any signal applied to the REF terminal should be very low (5 ). A source impedance of only 10 at the REF pin reduces the INA148's CMR to approximately 74 dB. High CMR can be restored if a resistor is added in series with the amplifier's positive input terminal (pin 3). This resistor should be 19 times the source impedance that drives the REF pin. For example, if the REF pin sees a source impedance of 10 , a resistor of 190 should be added in series with pin 3. Preferably, the offset trim voltage applied to the REF pin should be buffered with an amplifier such as an OPA237 (see Figure 3). In this case, the op amp output impedance is low enough that no external resistor is needed to maintain the INA148's excellent CMR. 10 Submit Documentation Feedback Copyright (c) 2009-2011, Texas Instruments Incorporated Product Folder Link(s): INA148-Q1 INA148-Q1 SBOS472A - MARCH 2009 - REVISED OCTOBER 2011 www.ti.com +15 V 7 2 V-IN 1 MW 50 kW 50 kW VO = (V+IN - V-IN) 2.7778 kW 6 A1 3 V+IN VO 52.6316 kW 1 MW INA148 4 VREF 1 +15 V -15 V OPA237 100 kW 100 kW 15-mV Offset Trim Range, RTI 100 W -15 V Figure 3. Preferred Offset Trim Circuit Input Impedance The input resistor network determines the impedance of each of the INA148 inputs. It is approximately 1 M. Unlike an instrumentation amplifier, signal source impedances at the two input terminals must be nearly equal to maintain good common-mode rejection. A mismatch between the two inputs' source impedances causes a differential amplifier's common-mode rejection to be degraded. With a source impedance imbalance of only 500 , CMR can fall to approximately 66 dB. Figure 4 shows a common application--measuring power supply current through a shunt resistor (RS). A shunt resistor creates an unbalanced source resistance condition that can degrade a differential amplifier's common mode rejection. +15 V 7 Load 2 1 MW 50 kW 50 kW IL VO = I L x R S 2.7778 kW 6 RC VO A1 RS 3 52.6316 kW 1 MW INA148 VCM 200 V 4 1 -15 V Make RC = RS if RS 100 W Figure 4. Shunt-Resistor Current Measurement Circuit Unless the shunt resistor is less than approximately 100 , an additional equal compensating resistor (RC) is recommended to maintain input balance and high CMR.

This is because the internal resistor network is laser-trimmed for accurate voltage divider ratios, but not necessarily to absolute values. Input resistors are shown as 1 M, however, this is only their nominal value. In practice, the input resistors' absolute values may vary by as much as 30%. The two input resistors match to about 5%, so adding compensating resistors greater than 5 k can cause a serious mismatch in the resulting resistor network voltage divider ratios, thus degrading CMR. Attempts to extend the INA148 input voltage range by adding external resistors is not recommended for the reasons described in the previous paragraph. CMR suffers serious degradation unless the resistors are carefully trimmed for CMR and gain. This is an iterative adjustment and can be tedious and time consuming.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
