DESCRIPTION

The OPA734 and OPA735 series of CMOS operational

amplifiers use auto-zeroing techniques to simultaneously

provide low offset voltage (5

µV max) and near-zero drift

over time and temperature. These miniature, high-preci-

sion, low quiescent current amplifiers offer high input

impedance and rail-to-rail output swing within 50mV of the

rails. Either single or bipolar supplies can be used in the

range of +2.7V to +12V (

±1.35V to ±6V). They are

optimized for low-voltage, single-supply operation.

The OPA734 family includes a shutdown mode. Under

logic control, the amplifiers can be switched from normal

operation to a standby current that is 9

µA (max) and the

output placed in a high-impedance state.

The single version is available in the MicroSIZE SOT23-5

(SOT23-6 for shutdown version) and the SO-8 packages.

The dual version is available in the MSOP-8 and SO-8

packages (MSOP-10 only for the shutdown version). All

versions are specified for operation from −40

°C to +85°C.
