3 Description
The OPAx333 series of CMOS operational amplifiers
use a proprietary auto-calibration technique to
simultaneously provide very low offset voltage
(10 μV, maximum) and near-zero drift over time and
temperature. These miniature, high-precision, low
quiescent current amplifiers offer high-impedance
inputs that have a common-mode range 100 mV
beyond the rails, and rail-to-rail output that swings
within 50 mV of the rails. Single or dual supplies as
low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) can
be used. These devices are optimized for low-
voltage, single-supply operation.
The OPAx333 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 5-pin
SOT-23, SOT, and 8-pin SOIC packages, while the
OPA2333 (dual version) is available in the 8-pin
VSON, SOIC, and VSSOP packages. All versions are
specified for operation from –40°C to 125°C.
