GENERAL DESCRIPTION

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

and 18 V power supply voltages. It uses the Analog Devices,

Inc., patented DigiTrim? trimming technique, which achieves low

offset voltage. Additionally, the unique design architecture of the

ADA4661-2-KGD 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-KGD is specified over the extended industrial

temperature range (?40°C to +125°C). Additional application and

technical information can be found in the ADA4661-2 data sheet.

Known Good Die (KGD): these die are guaranteed to data sheet

specifications.
