ADA4661-2ARMZ-RL

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. Its performance is guaranteed at 3V, 10V, and 18V 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 allows it to have excellent power supply rejection, common-mode rejection, and offset voltage when operating in the common-mode voltage range of -VSY +1.5V to +VSY -1.5V. Application includes current shunt monitors, active filters, portable medical equipment, buffer/level shifting, high impedance sensor interfaces, battery powered instrumentation.
