GENERAL DESCRIPTION

The OP290 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 OP290 to accommodate input signals

down to ground in single-supply operation. The OP290 output

swing also includes ground when operating from a single

supply, enabling zero-in, zero-out operation.

common-mode rejection is better than 100 dB. The power

supply rejection ratio of under 5.6 μV/V minimizes offset

voltage changes experienced in battery-powered systems. The

low offset voltage and high gain offered by the OP290 bring

precision performance to micropower applications. The

minimal voltage and current requirements of the OP290 suit it

for battery- and solar-powered applications, such as portable

instruments, remote sensors, and satellites. For a single op amp,

see the OP90; for a quad, see the OP490.

The OP290 draws less than 20 μA of quiescent supply current

per amplifier, while being able to deliver over 5 mA of output

current to a load. Input offset voltage is below 200 μV, eliminat-

ing the need for external nulling. Gain exceeds 700,000 and
