DESCRIPTION

The OPA234 series low cost op amps are ideal for
single supply, low voltage, low power applications. The
series provides lower quiescent current than older
“1013”-type products and comes in current industry­standard packages and pinouts. The combination of low
offset voltage, high common-mode rejection, high power
supply rejection, and a wide supply range provides
excellent accuracy and versatility. Single, dual, and
quad versions have identical specifications for maxi­mum design flexibility. These general purpose op amps
are ideal for portable and battery powered applications.

OPA234 series op amps operate from either single or
dual supplies. In single supply operation, the input com­mon-mode range extends below ground and the output
can swing to within 50mV of ground. Excellent phase
margin makes the OPA234 series ideal for demanding
applications, including high load capacitance. Dual and
quad designs feature completely independent circuitry
for lowest crosstalk and freedom from interaction.

Single version packages are DIP-8, SO-8 surface-mount,
and a space-saving MSOP-8 surface-mount. Dual pack­ages are DIP-8 and SO-8 surface-mount. Quad pack­ages are DIP-14 and SO-14 surface-mount. All are
specified for –40°C to +85°C operation.
