AD8605ACBZ-REEL

Overview

The AD8605ACBZ-REEL is a single-channel, precision, low-noise CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device utilizes Analog Devices' patented DigiTrim® trimming technique to achieve superior precision without laser trimming. Key electrical specifications include a maximum offset voltage of 65 µV, a maximum input bias current of 1 pA, and a voltage noise density of 8 nV/√Hz at 1 kHz. It offers a unity-gain bandwidth of 10 MHz and a slew rate of 5 V/µs. The component is housed in a 5-ball WLCSP package and is specified for operation across the extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify that the ordering suffix 'CBZ' corresponds to the 5-ball WLCSP package configuration as defined in the official Analog Devices datasheet. Confirm that the 'REEL' designation indicates tape-and-reel packaging. Ensure the component meets RoHS compliance requirements by checking the specific manufacturing lot documentation against the manufacturer's standards.

Selection Notes

Select this component when designing circuits requiring high precision and low noise within a compact footprint. The 5-ball WLCSP package provides the smallest available surface area for surface-mounted operational amplifiers. Consider the device for applications demanding rail-to-rail performance and extended industrial temperature stability, such as portable medical devices or battery-operated sensors.
