The OP97 maintains the standards of performance set by the OP07 while utilizing only 600 A supply current, less than 1/6 that of an OP07. Offset voltage is an ultralow 25 V, and drift over temperature is below 0.6 V/C. External offset trimming is not required in the majority of circuits. Common-mode rejection and power supply rejection are also improved with the OP97, at 114 dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from 2.25 V to 20 V, and the minimal power requirements of the OP97 combine to make the OP97 a preferred device for portable and battery-powered instruments. Improvements have been made over OP07 specifications in several areas. Notable is bias current, which remains below 250 pA over the full military temperature range. The OP97 is ideal for use in precision long-term integrators or sample-andhold circuits that must operate at elevated temperatures. The OP97 conforms to the OP07 pinout, with the null potentiometer connected between Pin 1 and Pin 8 with the wiper to V+. The OP97 upgrades circuit designs using AD725, OP05, OP07, OP12, and PM1012 type amplifiers. It may replace 741type amplifiers in circuits without nulling or where the nulling circuitry has been removed. Rev. G Information furnished by Analog Devices is believed to be accurate and reliable.

The OP97 can be substituted directly into OP07, OP77, AD725, and PM1012 sockets with improved performance and/or less power dissipation and can be inserted into sockets conforming to the 741 pinout if nulling circuitry is not used. Generally, nulling circuitry used with earlier generation amplifiers is rendered superfluous by the extremely low offset voltage of the OP97 and can be removed without compromising circuit performance. Extremely low bias current over the full military temperature range makes the OP97 attractive for use in sample-and-hold amplifiers, peak detectors, and log amplifiers that must operate over a wide temperature range. Balancing input resistances is not necessary with the OP97. Offset voltage and TCVOS are degraded only minimally by high source resistance, even when unbalanced. The input pins of the OP97 are protected against large differential voltage by back-to-back diodes. Current-limiting resistors are not used to maintain low noise performance. If differential voltages above 1 V are expected at the inputs, series resistors must be used to limit the current flow to a maximum of 10 mA. Common-mode voltages at the inputs are not restricted and may vary over the full range of the supply voltages used. The OP97 requires very little operating headroom about the supply rails and is specified for operation with supplies as low as 2 V. Typically, the common-mode range extends to within 1 V of either rail. The output typically swings to within 1 V of the rails when using a 10 k load. Offset nulling is achieved utilizing the same circuitry as an OP07. A potentiometer between 5 k and 100 k is connected between Pin 1 and Pin 8 with the wiper connected to the positive supply. The trim range is between 300 V and 850 V, depending upon the internal trimming of the device. +V 1 RPOT = 5k TO 100k 8 2 7 OP97 6 4 -V COC 00299-029 5 3 Figure 29. Optional Input Offset Voltage Nulling and Overcompensation Circuit Rev. G | Page 11 of 16 OP97 AC PERFORMANCE The ac characteristics of the OP97 are highly stable over its full operating temperature range. Unity-gain small-signal response is shown in Figure 30. Extremely tolerant of capacitive loading on the output, the OP97 displays excellent response even with 1000 pF loads (see Figure 31). In large signal applications, the input protection diodes effectively short the input to the output during the transients if the amplifier is connected in the usual unity-gain configuration. The output enters short-circuit current limit, with the flow going through the protection diodes. Improved large signal transient response is obtained by using a feedback resistor between the output and the inverting input. Figure 32 shows the large-signal response of the OP97 in unitygain with a 10 k feedback resistor. The unity-gain follower circuit is shown in Figure 33. 100 90 10 2V 20s 00299-032 0% Figure 32.

Its tightly trimmed offset voltage and minimal bias current result in virtually no degradation of linearity, even over wide temperature ranges. Figure 36 shows a versatile monitor circuit that can typically sense current at any point between the 15 V supplies. This makes it ideal for sensing current in applications such as full bridge drivers where bidirectional current is associated with large common-mode voltage changes. The 114 dB CMRR of the OP97 makes the contribution of the amplifier to commonmode error negligible, leaving only the error due to the resistor ratio inequality. Ideally, R2/R4 = R3/R5. High impedance circuitry is extremely susceptible to RF pickup, line frequency hum, and radiated noise from switching power supplies. Enclosing sensitive analog sections within grounded shields is generally necessary to prevent excessive noise pickup. Twisted-pair cable aid in rejection of line frequency hum.

Current Monitor VOUT DIGITAL INPUTS RL 00299-036 To maintain the extremely high input impedances of the OP97, care must be taken in circuit board layout and manufacturing. Board surfaces must be kept scrupulously clean and free of moisture. Conformal coating is recommended to provide a humidity barrier. Even a clean PCB can have 100 pA of leakage currents between adjacent traces; therefore, use guard rings around the inputs. Guard traces are operated at a voltage close to that on the inputs, so that leakage currents are minimal. In noninverting applications, connect the guard ring to the commonmode voltage at the inverting input (Pin 2). In inverting applications, both inputs remain at ground, so that the guard trace should be grounded. Make guard traces on both sides of the circuit board. OP97 +15V The digitally programmable gain amplifier shown in Figure 38 has 12-bit gain resolution with 10-bit gain linearity over the range of -1 to -1024.

A combination amplifier consisting of a high precision, slow device like the OP97 and a faster device such as the AD8610 results in uniformly accurate performance from dc to the high frequency limit of the AD8610, which has a gainbandwidth product of 25 MHz. The circuit shown in Figure 39 accomplishes this, with the AD8610 providing high frequency amplification and the OP97 operating on low frequency signals and providing offset correction.
