描述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(1). 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 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.特性Low Offset Voltage: 26 µV (Maximum) 0.01-Hz to 10-Hz Noise: 1.5 µVPP Quiescent Current: 50 µA Single-Supply Operation Supply Voltage: 1.8 V to 5.5 V Rail-to-Rail Input and Output Supports Extreme Temperature Applications Controlled Baseline One Assembly/Test Site One Fabrication Site Available in Extreme (–55°C to 210°C) Temperature Range(1) Extended Product Life Cycle Extended Product-Change Notification Product Traceability Texas Instruments’ high temperature products use highly optimized silicon (die) solutions with design and process enhancements to maximize performance over extended temperatures.
