ADA4661-2 / ADA4666-2 RRIO Operational Amplifiers

ADA4661-2 / ADA4666-2 RRIO Operational Amplifiers

The ADA4661-2 and ADA4666-2 from Analog Devices are dual, rail-to-rail input/output amplifiers optimized for low-power, high-bandwidth, and wide-operating supply voltage range applications.

The ADA4661-2 and ADA4666-2 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.

The ADA4661-2 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 and, 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 and ADA4666-2 are specified over the extended industrial temperature range (-40°C to +125°C) and available in 8-lead MSOP and 8-lead LFCSP (3 mm × 3 mm) packages.
