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.
