DESCRIPTION
The OPA333 series of CMOS operational amplifiers
use a proprietary auto-calibration technique to
simultaneously provide very low offset voltage (10
μV, max) 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 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 (3 mm ×
3 mm), MSOP-8, and SO-8 packages. All versions
are specified for operation from –40°C to +125°C.
