Description
- The OPA211 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.
- The extremely low voltage and low current noise, high-speed, and wide output swing of the OPA211 series make these devices an excellent choice as a loop filter amplifier in PLL applications.
- In precision data acquisition applications, the OPA211 series of operational amplifiers provides 700-ns settling time to 16-bit accuracy throughout 10-V output swings. This ac performance, combined with only 125 µV of offset and 0.35 µV/°C of drift over temperature, makes the OPA211 ideal for driving high-precision 16-bit analog-to-digital converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (DACs).
- The OPA211 series is specified over a wide dual-power supply range of ±2.25 to ±18 V, or for single-supply operation from 4.5 to 36 V.
- The OPA211 is available in the small SON-8 (3 mm × 3 mm), VSSOP-8, and SOIC-8 packages. A dual version, the OPA2211, is available in the SON-8 (3 mm × 3 mm) or an SO-8 PowerPAD™ package. This series of operational amplifiers is specified from TA = –40°C to +125°C.
- 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
- Wide Supply Range: ±2.25 to ±18 V, 4.5 to 36 V
- Rail-to-Rail Output
- Output Current: 30 mA
- SON-8 (3 mm × 3 mm), VSSOP-8, and SOIC-8
