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.
