AD706JRZ-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD706JRZ-REEL is a dual precision bipolar operational amplifier manufactured by Analog Devices Inc. It features superbeta input transistors providing picoampere-level bias currents with low temperature drift, eliminating the need for balancing resistors. The device operates within a supply voltage range of ±2 V to ±18 V and delivers a unity gain crossover frequency of 0.8 MHz with a slew rate of 0.15 V/µs. Key electrical specifications include a maximum initial offset voltage of 100 µV, an input bias current of 200 pA, and a quiescent current of 750 µA. It is housed in an 8-lead SOIC package and rated for commercial operation from 0°C to +70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Utilizes superbeta bipolar input transistors to achieve JFET-level input bias currents while maintaining significantly lower bias current drift over temperature compared to standard JFET amplifiers.
• Provides high DC precision with microvolt-level offset voltage and low noise characteristics suitable for applications requiring chopper-stabilized performance without inherent chopper noise.
• Internally compensated for unity gain stability and designed for low power consumption, making it well-suited for high-density board layouts.

Instrumentation, Op Amps, Buffer Amps Applications

• Low frequency active filters
• Precision instrumentation
• Precision integrators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific ordering suffix corresponds to the required tape and reel packaging format (e.g., 7-inch or 13-inch reels) as defined in the manufacturer's ordering guide. Confirm the component grade matches the intended operating temperature range requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when circuit design requires ultra-low input bias current combined with minimal drift across varying temperatures. It serves as a direct replacement for circuits traditionally utilizing chopper amplifiers where low-frequency noise must be minimized. Ensure the application does not exceed the differential input voltage limits without external protection.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD706 family of dual precision op amps. The 'J' designation indicates the commercial temperature grade (0°C to +70°C), distinguishing it from the 'A' grade which supports extended industrial ranges. The quad version of this architecture is available as the AD704.
