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.ApplicationsCurrent shunt monitorsActive filtersPortable medical equipmentBuffer/level shiftingHigh impedance sensor interfacesBattery powered instrumentation
