ADA4817-2ACPZ-R2

Overview

The ADA4817-2ACPZ-R2 is a dual-channel, unity-gain stable, ultrahigh-speed voltage feedback operational amplifier featuring FET inputs. Manufactured using the proprietary eXtra fast complementary bipolar (XFCB) process, it delivers a -3 dB bandwidth of 1050 MHz and a slew rate of 870 V/µs at ±5 V supplies. The device exhibits low input noise with 4 nV/√Hz voltage noise and 2.5 fA/√Hz current noise. It operates on supply voltages ranging from 5 V to 10 V, drawing 19 mA quiescent current per amplifier, and includes dedicated power-down pins to reduce consumption below 2 mA when inactive.

Feature Summary

Ultrahigh speed performance with 1050 MHz bandwidth and 870 V/µs slew rate enabled by XFCB technology
Ultra-low noise characteristics including 4 nV/√Hz voltage noise and 2.5 fA/√Hz current noise
Integrated power-down functionality allowing quiescent current reduction from 19 mA to under 2 mA
Low distortion pinout design in 16-lead LFCSP package to improve second harmonic distortion

Applications

Photodiode amplifiers
Data acquisition front ends
ADC drivers
Output buffers
Active filters

Procurement Notes

Verify that the ordering suffix ACPZ-R2 corresponds to the 16-lead LFCSP package and reel packaging configuration. Confirm the component meets RoHS compliance standards for the specific manufacturing lot. Ensure the datasheet revision matches the required specifications for your circuit design. Check for any recent product change notifications regarding pin functions or thermal characteristics.

Selection Notes

Select this amplifier for applications requiring high bandwidth and minimal signal degradation. The dual-channel configuration allows for cost-effective implementation of differential circuits. Consider the exposed pad for thermal management during high-power operation. Evaluate the power-down feature if system energy efficiency is critical during idle periods.

Part Context

This component belongs to the ADA4817 series of FastFET op amps, which also includes the single-channel ADA4817-1. Both variants share identical electrical characteristics but differ in package options and channel count. The series is designed for wideband transimpedance applications and high-resolution data acquisition systems requiring precision and speed.
