The OPA333 series of CMOS operational amplifiers uses a proprietary auto-calibrationtechnique 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 op amps use an auto-calibration technique with a time-continuous 350kHz op amp in the signal path. This amplifier is zero-corrected every 8μs using a proprietarytechnique. Upon powerup, the amplifier requires approximately 100μs to achieve specifiedVOS accuracy. This design has no aliasing or flicker noise.
