The low cost INA133 and INA2133 provide this precision circuit function without using an expensive precision network. The INA133 and INA2133 are high slew rate, unitygain difference amplifiers consisting of a precision op amp with a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. They operate over a wide supply range, 2.25V to 18V (+4.5V to +36V single supply), and input common-mode voltage range extends beyond the positive and negative supply rails. The single version, INA133, package is the SO-8 surface mount. The dual version, INA2133, package is the SO-14 surface mount. Both are specified for operation over the extended industrial temperature range, -40C to +85C. Operation is from -55C to +125C.

The INA133 and INA2133 are high-speed difference amplifiers suitable for a wide range of general purpose applications. Figure 1 shows the basic connections required for operation of the INA133. Decoupling capacitors are strongly recommended in applications with noisy or high impedance power supplies. The capacitors should be placed close to the device pins as shown in Figure 1. All circuitry is completely independent in the dual version assuring lowest crosstalk and normal behavior when one amplifier is overdriven or short-circuited. OPERATING VOLTAGE The INA133 and INA2133 operate from single (+4.5V to +36V) or dual (2.25V to 18V) supplies with excellent performance. Specifications are production tested with 5V and 15V supplies. Most behavior remains unchanged throughout the full operating voltage range. Parameters which vary significantly with operating voltage are shown in the Typical Performance Curves. As shown in Figure 1, the differential input signal is connected to pins 2 and 3. The source impedances connected to the inputs must be nearly equal to assure good commonmode rejection. A 5 mismatch in source impedance will degrade the common-mode rejection of a typical device to approximately 80dB (a 10 mismatch degrades CMR to 74dB). If the source has a known impedance mismatch, an additional resistor in series with the opposite input can be used to preserve good common-mode rejection. INPUT VOLTAGE The INA133 and INA2133 can accurately measure differential signals that are above and below the supply rails. Linear common-mode range extends from 2 * (V+)-3V to 2 * (V-) +3V (nearly twice the supplies). See the typical performance curve, "Input Common-Mode Voltage vs Output Voltage." OFFSET VOLTAGE TRIM The INA133's internal resistors are accurately ratio trimmed to match. That is, R1 is trimmed to match R2 and R3 is trimmed to match R4. However, the absolute values may not be equal (R1 + R2 may be slightly different than R3 + R4). Thus, large series resistors on the input (greater than 250), even if well matched, will degrade common-mode rejection. The INA133 and INA2133 are laser trimmed for low offset voltage and drift. Most applications require no external offset adjustment. Figure 2 shows an optional circuit for trimming the output offset voltage. The output is referred to the output reference terminal (pin 1), which is normally grounded. A voltage applied to the Ref terminal will be summed with the output signal. This can be used to null offset voltage as shown in Figure 2. The source impedance of a signal applied to the Ref terminal should be less than 10 to maintain good common-mode rejection. Circuit board layout constraints might suggest possible variations in connections of the internal resistors. For instance, it appears that pins 1 and 3 could be interchanged. However, because of the ratio trimming technique used (see paragraph above) CMRR will be degraded.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
