ADA4817-2ACPZ-RL

Overview

The ADA4817-2ACPZ-RL is a dual-channel, low noise, ultrahigh speed voltage feedback operational amplifier featuring FET inputs. It utilizes the proprietary eXtra fast complementary bipolar (XFCB) process to achieve a −3 dB bandwidth of 1050 MHz at unity gain and a slew rate of 870 V/µs. The device offers an input voltage noise density of 4 nV/√Hz and an exceptionally low input current noise of 2.5 fA/√Hz. Designed for operation on single or dual supplies ranging from 5 V to 10 V, it includes dedicated power-down pins to reduce quiescent current. The component is housed in a 16-lead LFCSP package with an exposed pad for thermal management.

• Ultra-low noise characteristics including 4 nV/√Hz voltage noise and 2.5 fA/√Hz current noise
• Integrated power-down functionality to minimize supply current consumption
• Low distortion pinout design to improve second harmonic distortion and simplify layout

Applications

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

Procurement Notes

Verify that the ordering suffix ACPZ corresponds to the 16-lead LFCSP package variant. Confirm the specific revision level matches system requirements. Ensure ESD precautions are observed during handling due to the sensitivity of the FET input stage. Check datasheet specifications for absolute maximum ratings regarding supply voltage and junction temperature limits before integration.

Selection Notes

Select this component when high bandwidth and minimal noise are critical for signal integrity. The dual configuration allows for cost-effective implementation of differential circuits. Consider the 16-lead LFCSP package for its thermal advantages and low distortion pinout. Evaluate the need for power-down features if system energy efficiency is a priority. Ensure the application operates within the specified 5 V to 10 V supply range.
