OPA2328
Overview
The single-channel OPA328 and dual-channel OPA2328 (OPAx328) are a new generation family of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth. The OPAx328 have a linear input stage with zerocrossover distortion that delivers excellent commonmode rejection ratio (CMRR) of 120dB (typical) over the full input range.
- Precision with zero-crossover distortion: - Low offset voltage: 50µV (maximum) - High CMRR: 120dB - Rail-to-rail I/O
- Wide bandwidth: 40MHz
- Low input bias current: 1pA (maximum)
- Low noise: 6.1nV/√Hz at 10kHz
- Slew rate: 30V/µs
- Fast 0.01% settling time: 180ns
- Single-supply voltage range: 2.2V to 5.5V
- Unity-gain stable
