The ADA4661-2ARMZ is a precision dual Operational Amplifier with rail-to-rail input/output. It is optimized for low power, high bandwidth and wide operating supply voltage range applications. 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 to +VSY -1.5V.
