OPA211
Overview
The OPAx211 series of precision operational amplifiers achieves very low 1.1-nV/√Hz noise density with a supply current of only 3.6 mA. This series also offers rail-to-rail output swing, which maximizes dynamic range.
- 1 Low voltage noise: 1.1 nV/√Hz at 1 kHz
- Input voltage noise: 80 nVPP (0.1 to 10 Hz)
- THD + N: -136 dB (G = 1, ƒ = 1 kHz)
- Offset voltage: 125 μV (maximum)
- Offset voltage drift: 0.35 μV/°C (typical)
- Low supply current: 3.6 mA/Ch (typical)
- Unity-gain stable
- Gain bandwidth product: - 80 MHz (G = 100) - 45 MHz (G = 1)
- Slew rate: 27 V/μs
- 16-Bit settling: 700 ns
