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 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.
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.
