ADA4922-1ACPZ-RL

Overview

The ADA4922-1ACPZ-RL is a high-voltage differential driver designed for 16-bit to 18-bit ADCs with differential input ranges up to ±20 V. It converts single-ended signals to differential outputs with a fixed gain of 2, requiring no external components. Operating on a supply voltage range of 5 V to 26 V, it delivers a 38 MHz bandwidth and low output noise of 12 nV/√Hz. The device features an integrated disable function and operates within the -40°C to +85°C temperature range.

Feature Summary

• Converts single-ended inputs to differential outputs with a fixed gain of 2 without external components
• Supports wide supply voltages from 5 V to 26 V for driving high-resolution ADCs
• Includes a dedicated disable pin to minimize power consumption when inactive

Applications

• High voltage data acquisition systems
• Industrial instrumentation
• Spectrum analysis
• Automated test equipment (ATE)
• Medical instruments

Procurement Notes

Verify the specific package option against the ordering guide. The ACPZ suffix indicates the 8-lead Lead Frame Chip Scale Package (LFCSP). Confirm that the reel quantity matches the required production volume. Ensure the RoHS-compliant marking code aligns with environmental regulations. Cross-reference the datasheet revision to confirm current specifications.

Selection Notes

Select this component when driving 16-bit or 18-bit ADCs requiring differential inputs from single-ended sources. It is suitable for applications needing high common-mode rejection and low distortion at high supply voltages. Consider the internal feedback network power dissipation during thermal design. Verify that the capacitive load drive capability meets the downstream circuit requirements.

Part Context

This part belongs to the ADA4922 family of high-voltage differential drivers manufactured by Analog Devices. It utilizes the proprietary second-generation XFCB process to achieve excellent noise and distortion performance. The device is available in both SOIC and LFCSP packages with exposed paddles for efficient heat transfer.
