- AEC-Q100 qualified for automotive applications:
- Temperature grade 1: –40°C to +125°C, TA
- Low offset voltage: 10 μV (maximum)
- 0.01-Hz to 10-Hz noise: 1.1 μVPP
- Quiescent current: 17 μA
- Single-supply operation
- Supply voltage: 1.8 V to 5.5 V
- Rail-to-rail input and output
- Microsize 5-pin SOT-23 (DBV) package
The OPA333-Q1 CMOS operational amplifier uses a proprietary autocalibration technique to simultaneously provide verylow offset voltage (10 μV maximum) and near-zero drift over time and temperature. This miniature, high-precision, low-quiescent-current amplifier offers high-impedance inputs that have a common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. The device can use single or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and is optimized for low-voltage single-supply operation.
The OPA333-Q1 device 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.
