  • 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.
