ADA4692-2ACPZ-R7

Overview

The ADA4692-2ACPZ-R7 is a dual-channel, rail-to-rail output operational amplifier from Analog Devices. It operates on a single supply of 2.7 V to 5 V or dual supplies of ±1.35 V to ±2.5 V. Key electrical specifications include a typical gain bandwidth product of 3.6 MHz, a typical supply current of 180 μA per amplifier, and a typical input bias current of 0.5 pA. The device features a typical voltage noise density of 16 nV/√Hz at 1 kHz and an offset voltage drift of 4 μV/°C maximum over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail output capability for maximizing dynamic range in low-voltage applications
• Micropower consumption with very low input bias currents suitable for high-impedance sources
• Low noise performance combined with wide bandwidth for precision signal conditioning

Applications

• Photodiode amplifiers
• Sensor amplifiers
• ADC drivers
• Active filters
• Portable audio equipment

Procurement Notes

Verify the specific package variant (LFCSP vs SOIC) matches the design footprint, as the family includes multiple packages. Confirm the suffix indicates the reel packaging format required for automated assembly. Ensure the operating environment stays within the specified -40°C to +125°C range for guaranteed performance parameters.

Selection Notes

Select this component when low power and low noise are critical simultaneously. It is distinct from the ADA4691 series which includes shutdown functionality; this part lacks shutdown pins. Consider the 8-lead LFCSP or SOIC options based on board space constraints. Verify that the 3.6 MHz bandwidth meets the system's frequency requirements without excessive power draw.

Part Context

This device belongs to the ADA469x family of micropower, precision operational amplifiers. It serves as the dual-channel, non-shutdown counterpart to the ADA4691-2. The family addresses applications requiring high impedance inputs and low distortion in portable, battery-powered systems where power efficiency is paramount.

FAQ

Does the ADA4692-2 have a shutdown pin?

No, the ADA4692-2 does not feature shutdown pins. The ADA4691-2 variant includes independent shutdown pins for further current reduction.

What is the input common-mode voltage range?

The input common-mode voltage extends below the negative supply rail by 0.3 V and up to the positive supply rail minus approximately 0.1 V to 0.3 V depending on the supply voltage.
