OP490 Overview
Input voltage range includes the negative rail allowing the OP490 to acmodate input signals down to ground in single-supply operation. The OP490’s output swing also includes ground when operating from a single supply, enabling “zero-in, zero-out” operation. The quad OP490 draws less than 20 µA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5 mA of output current to a load.
