GENERAL DESCRIPTION

The ADA4510-21 is a dual-channel, 40 V, high precision, low input

bias current, low offset voltage, low offset voltage drift, low noise,

rail-to-rail input and output operational amplifier that can be used at

any point of the signal chain, including sensing, conditioning, and

output drive. Through the use of Analog Devices, Inc., proprietary

DigiTrim™ technique, the ADA4510-2 achieves best-in-class low

offset drift (±70 nV/°C typical, ±500 nV/°C maximum) and low offset

voltage (±5 μV typical, ±20 μV maximum), simplifying temperature

calibrations in precision designs.

The ADA4510-2 delivers excellent DC precision and outstanding

AC performance, making it a top choice for a wide variety of

signal chain applications. By integrating a robust mux-compatible

architecture, the ADA4510-2 effectively solves common system

distortion and settling problems and provides the superior accuracy

required in multiplexed multichannel precision signal chains. The

ADA4510-2 is specified from −40°C to +85°C and −40°C to +125°C

and is available in an 8-lead, SOIC_N and 8-lead, MSOP.
