DESCRIPTION
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 common-mode 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, available
Q2 ’06) and SO-8 packages. All versions are specified for
operation from −40°C to +125°C.
