ADA4817-1ACPZ-RL

Overview

The ADA4817-1ACPZ-RL is a single-channel, unity-gain stable, ultrahigh-speed voltage feedback operational amplifier with FET inputs. It features a 1050 MHz −3 dB bandwidth and an 870 V/µs slew rate. The device exhibits low input noise of 4 nV/√Hz at 100 kHz and 2.5 fA/√Hz current noise. It operates on supply voltages from 5 V to 10 V in either single or dual configurations. The component includes a dedicated power-down pin to reduce quiescent current from 19 mA to below 2 mA. It is housed in an 8-lead LFCSP package with an exposed thermal pad.

Procurement Notes

Verify the specific ordering suffix ACPZ-RL against the manufacturer's official documentation to confirm the package type (LFCSP) and reel packaging configuration. Ensure the procurement channel provides valid traceability for Analog Devices components. Confirm that the received units match the Rev. I datasheet specifications regarding electrical parameters and physical dimensions before integration into production designs.

Selection Notes

Select this component for applications requiring high-speed signal processing with minimal noise introduction. The FET input stage offers high input impedance suitable for sensitive sources. Consider the 5 V to 10 V operating range when designing power supplies. The availability of a power-down mode makes it suitable for battery-operated systems where standby power consumption must be minimized during inactive periods.

Part Context

This part belongs to the ADA4817 family developed using the eXtra Fast Complementary Bipolar (XFCB) process. The family includes the dual-channel ADA4817-2 variant. These amplifiers are designed to combine high speed with low noise, addressing the needs of wideband transimpedance applications. The architecture utilizes an H-bridge output stage to achieve high slew rates while maintaining low distortion levels across various load conditions.
