The OP-97 is a low-power alternative to the industry-standard OP-07 precision amplifier. The OP-97 maintains the standards of performance set by the OP-07 while utilizing only 600µA supply current, less than 1/6 that of an OP-07. Offset voltage is an ultra-low 25µV, and drift over temperature is below 0.6µV/°C. External offset trimming is not required in the majority of circuits.Improvements have been made over OP-07 specifications in several areas. Notable is bias current, which remains below 250pA over the full military temperature range. The OP-97 is ideal for use in precision long-term integrators or sample-and-hold circuits that must operate at elevated temperatures.Common-mode rejection and power-supply rejection are also improved with the OP-97, at 114dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from ±2.25V to ±20V and the OP-97's minimal power requirements combine to make the OP-97 a preferred device for portable and battery-powered instruments.The OP-97 conforms to the OP-07 pinout, with the null potentimeter connected between pins 1 and 8 with the wiper to V+. The OP-97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers. It may replace 741-type amplifiers in circuits without nullling or where the nulling circuitry has been removed.

The AD532 is the first pretrimmed single chip monolithic multiplier/divider. It guarantees a maximum multiplying error of ±1.0% and a ±10 V output voltage without the need for any external trimming resistors or output op amp. Because the AD532 is internally trimmed, its simplicity of use provides design engineers with an attractive alternative to modular multipliers, and its monolithic construction provides significant advantages in size, reliability and economy. Further, the AD532 can be used as a direct replacement for other IC multipliers that require external trim networks (such as the AD530).APPLICATIONS Multiplication, division, squaring, square rooting Algebraic computation Power measurements Instrumentation applications Available in chip form

The AD534 is a monolithic laser trimmed four-quadrant multiplier divider having accuracy specifications previously found only in expensive hybrid or modular products. A maximum multiplication error of ±0.25% is guaranteed for the AD534L without any external trimming. Excellent supply rejection, low temperature coefficients and long-term stability of the on-chip thin film resistors and buried Zener reference preserve accuracy even under adverse conditions of use. It is the first multiplier to offer fully differential, high impedance operation on all inputs, including the Z input, a feature that greatly increases its flexibility and ease of use. The scale factor is pretrimmed to the standard value of 10.00 V; by means of an external resistor, this can be reduced to values as low as 3 V.The wide spectrum of applications and the availability of several grades commend this multiplier as the first choice for all new designs. The AD534J (±1% maximum error), AD534K (±0.5% maximum), and AD534L (±0.25% maximum) are specified for operation over the 0°C to +70°C temperature range. The AD534S (±1% maximum) and AD534T (±0.5% maximum) are specified over the extended temperature range, −55°C to +125°C. All grades are available in hermetically sealed TO-100 metal cans and SBDIP packages.

The AD706 is a dual, low power, bipolar op amp that has thelow input bias current of a JFET amplifier, but which offers asignificantly lower IB drift over temperature. It utilizes superbetabipolar input transistors to achieve picoampere input bias currentlevels (similar to FET input amplifiers at room temperature),while its IB typically only increases by 5 at 125°C (unlike aJFET amp, for which IB doubles every 10°C for a 1000×increase at 125°C).
