GENERAL DESCRIPTION

The ADA4661-2 is a dual, precision, rail-to-rail input/output

amplifier optimized for low power, high bandwidth, and wide

operating supply voltage range applications.

The ADA4661-2 performance is guaranteed at 3.0 V, 10 V,

and 18 V power supply voltages. It is an excellent selection for

applications that use single-ended supplies of 3.3 V, 5 V, 10 V, 12

V and 15 V, and dual supplies of ±2.5 V, ±3.3 V, and ±5 V. It

uses the Analog Devices, Inc., patented DigiTrim® trimming

technique, which achieves low offset voltage. Additionally, the

unique design architecture of the ADA4661-2 allows it to have

excellent power supply rejection, common-mode rejection, and

offset voltage when operating in the common-mode voltage

range of −VSY + 1.5 V to +VSY − 1.5 V.

The ADA4661-2 is specified over the extended industrial

temperature range (−40°C to +125°C) and is available in

8-lead MSOP and 8-lead LFCSP (3 mm × 3 mm) packages.
