GENERAL DESCRIPTION

The OP490 is a high-performance micropower quad op amp that operates from a single supply of 1.6 V to 36 V or from dual supplies of ±0.8 V to ±18 V. Input voltage range includes the negative rail allowing the OP490 to accommodate 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.
