1.8V, microPOWER CMOS OPERATIONAL AMPLIFIERS Zer-Drift Series
OPA333
The OPA333 series of CMOS operational amplifiers
uses a proprietary auto-calibration technique to simultaneously
provide very low offset voltage (10μV max)
and near-zero drift over time and temperature. These
miniature, high-precision, low quiescent current amplifiers
offer high-impedance inputs that have a commonmode
range 100mV beyond the rails and rail-to-rail output
that swings within 50mV of the rails. Single or dual
supplies as low as +1.8V (±0.9V) and up to +5.5V
(±2.75V) may be used. They are optimized for low-voltage,
single-supply operation.
The OPA333 family offers excellent CMRR without the
crossover associated with traditional complementary
input stages. This design results in superior performance
for driving analog-to-digital converters (ADCs)
without degradation of differential linearity.
The OPA333 (single version) is available in the SC70-5,
SOT23-5, and SO-8 packages. The OPA2333 (dual
version) is offered in DFN-8 (3mm x 3mm) and SO-8
packages. All versions are specified for operation from −40°C to +125°C.
