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 industry-

standard packages and pinouts. The combination of

low offset voltage, high common-mode rejection, high

power-supply rejection, and a wide supply range pro-

vides 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 appli-

cations.

OPA4234

The 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 de-

manding applications, including high load capacitance.

Dual and quad designs feature completely indepen-

dent circuitry for lowest crosstalk and freedom from

interaction.

Single version packages are in an SO-8 surface-mount

and a space-saving MSOP-8 surface-mount. Dual pack-

ages are in an SO-8 surface-mount. Quad packages

are in an SO-14 surface-mount. All are specified for

–40°C to +85°C operation.
