ADA4692-2ARZ-R7

Overview

The ADA4692-2ARZ-R7 is a dual, low-power, wideband operational amplifier featuring rail-to-rail output capability. It operates on a single supply from 2.7 V to 5 V or split supplies of ±1.35 V to ±2.5 V. The device offers a gain bandwidth product of 3.6 MHz and a typical supply current of 180 μA per amplifier. Key electrical characteristics include a typical input bias current of 0.5 pA, voltage noise density of 16 nV/√Hz at 1 kHz, and an offset voltage of 500 μV. It is specified over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail output stage provides maximum dynamic range for single-supply applications.
• Extremely low input bias current minimizes loading effects on high-impedance signal sources.
• Low power consumption enables extended battery life in portable systems.
• Wide bandwidth supports high-speed signal processing with low distortion.

Applications

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

Procurement Notes

Verify the package type matches the specific ordering suffix; the ARZ suffix indicates an 8-lead SOIC package. Confirm that the R7 suffix corresponds to the reel packaging format required for automated assembly processes. Ensure the component meets RoHS compliance standards as indicated by the Z suffix. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and revision level before procurement.

Selection Notes

Select this component when a dual-channel amplifier is required with rail-to-rail output swing and low power consumption. It is suitable for applications demanding low input bias current and moderate bandwidth. Consider alternative packages if space constraints require a smaller footprint than the SOIC-8. Verify that the supply voltage range aligns with the system's power rails and that the operating temperature range covers the intended environment.

Part Context

This component belongs to the ADA469x family of low-power, precision operational amplifiers manufactured by Analog Devices Inc. The family includes single, dual, and quad variants with varying shutdown capabilities. The ADA4692-2 specifically denotes the dual-channel version without shutdown pins, distinguishing it from the ADA4691-2 which includes independent shutdown controls for each channel.

Replacement Considerations

Direct replacements within the same family include the ADA4691-2 (with shutdown) and ADA4692-4 (quad version). Other compatible parts may include the ADA4691-4 or ADA4692-4 depending on channel count requirements. Verify pin compatibility and electrical specifications before substituting.
