Texas Instruments' high temperature products

utilize highly optimized silicon (die) solutions

with design and process enhancements to

maximize performance over extended

temperatures.

Custom temperature ranges available

The OPA2333 series of CMOS operational amplifiers uses a proprietary auto-calibration technique to

simultaneously provide very low offset voltage 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 150 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) may be used. They are optimized for low-voltage single-supply

operation.

The OPA2333 family offers excellent common-mode rejection ratio (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.
