The OP90 is a high performance, micropower 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. The input voltage range includes
the negative rail allowing the OP90 to accommodate input
signals down to ground in a single-supply operation. The OP90’s
output swing also includes a ground when operating from a
single-supply, enabling “zero-in, zero-out” operation.
The OP90 draws less than 20 μA of quiescent supply current,
while able to deliver over 5 mA of output current to a load. The
input offset voltage is below 150 μV eliminating the need for
external nulling. Gain exceeds 700,000 and 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 OP90 bring
precision performance to micropower applications. The minimal
voltage and current requirements of the OP90 suit it for battery
and solar powered applications, such as portable instruments,
remote sensors, and satellites.
