ADA4692-2ARZ-RL

Overview

The ADA4692-2ARZ-RL is a dual-channel, 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. Key electrical specifications include a typical gain-bandwidth product of 3.6 MHz, input bias current of 0.5 pA, and voltage noise density of 16 nV/√Hz at 1 kHz. The device offers a typical offset voltage of 500 μV with a maximum drift of 4 μV/°C over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail output stage enables full signal swing across the supply range.
• Very low input bias current minimizes loading effects on high-impedance sources.
• Low power consumption supports battery-operated portable applications.
• Wide bandwidth and low distortion ensure accurate signal processing.

Applications

• Photodiode amplifiers
• Sensor amplifiers for pyroelectric and IR sensors
• Portable audio devices such as MP3 players and smartphones
• ADC drivers and active filters

Procurement Notes

Verify the package type matches the required footprint, as this part number corresponds to the 8-lead SOIC_N variant. Confirm that the specific ordering suffix aligns with the desired reel quantity and tape-and-reel packaging configuration. Ensure the component meets RoHS compliance standards if required by the manufacturing process.

Selection Notes

Select this component when a combination of low power, wide bandwidth, and precision is required without shutdown functionality. The ADA4692-2 lacks the shutdown pins found in the ADA4691-2 variant. Consider the 8-lead SOIC package for standard surface-mount assembly processes requiring a wider pitch than LFCSP options.

Part Context

This device belongs to the ADA469x family of micropower operational amplifiers manufactured by Analog Devices. The family includes dual (ADA4691-2/ADA4692-2) and quad (ADA4691-4/ADA4692-4) configurations. The ADA4692-2 specifically denotes the version without shutdown control, distinguishing it from the ADA4691-2 which features independent shutdown pins for each channel.

Replacement Considerations

The ADA4691-2 serves as a functional substitute but includes additional shutdown pins. For quad configurations, the ADA4692-4 provides four channels in a 14-lead TSSOP package. Other family members like the ADA4691-4 offer quad channels with shutdown capabilities in a 16-lead LFCSP.
