The OP290GPZ  is a high performance micropower dual 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 OP290GPZ to accommodate input signals down to ground in single-supply operation. The OP290GPZ output swing also includes ground when operating from a single supply, enabling zero-in, zero-out operation.
