Description

The OPA734 and OPA735 series of CMOS operational amplifiers use auto-zeroing techniques to simultaneously provide low offset voltage (5µV max) and near-zero drift
over time and temperature. These miniature, high-precision, 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 device family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is 9µA (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.
