1.1nV/ãHz Noise, Low Power, Precision
Operational Amplifier in Small DFN-8 Package
23· LOW VOLTAGE NOISE: 1.1nV/ãHz at 1kHz The OPA211 series of precision operational
· INPUT VOLTAGE NOISE: amplifiers achieves very low 1.1nV/ãHz noise density
80nVPP (0.1Hz to 10Hz) with a supply current of only 3.6mA. This series also
· THD+N: –136dB (G = 1, f = 1kHz) offers rail-to-rail output swing, which maximizes dynamic range.
· OFFSET VOLTAGE: 125mV (max)
· OFFSET VOLTAGE DRIFT: 0.35mV/°C (typ) The extremely low voltage and low current noise, high speed, and wide output swing of the OPA211
· LOW SUPPLY CURRENT: 3.6mA/Ch (typ) series make these devices an excellent choice as a
· UNITY-GAIN STABLE loop filter amplifier in PLL applications.
· GAIN BANDWIDTH PRODUCT: In precision data acquisition applications, the
80MHz (G = 100) OPA211 series of op amps provides 700ns settling
45MHz (G = 1) time to 16-bit accuracy throughout 10V output swings.
· SLEW RATE: 27V/ms This ac performance, combined with only 125mV of offset and 0.35mV/°C of drift over temperature, makes
· 16-BIT SETTLING: 700ns the OPA211 ideal for driving high-precision 16-bit
· WIDE SUPPLY RANGE: analog-to-digital converters (ADCs) or buffering the
±2.25V to ±18V, +4.5V to +36V output of high-resolution digital-to-analog converters
· RAIL-TO-RAIL OUTPUT (DACs).
· OUTPUT CURRENT: 30mA The OPA211 series is specified over a wide
· DFN-8 (3mm × 3mm), MSOP-8, AND SO-8 dual-power supply range of ±2.25V to ±18V, or for single-supply operation from +4.5V to +36V.
The OPA211 is available in the small DFN-8 (3mm ×
· PLL LOOP FILTER 3mm), MSOP-8, and SO-8 packages. A dual version, · LOW-NOISE, LOW-POWER SIGNAL the OPA2211, is available in the DFN-8 (3mm × PROCESSING 3mm) or an SO-8 PowerPAD™ package. This series of op amps is specified from TA = –40°C to +125°C.
