SBOS377G – OCTOBER 2006 – REVISED MAY 2009 1.1nV/ √Hz Noise, Low Power, Precision Operational Amplifier in Small DFN-8 Package 23 • LOW VOLTAGE NOISE: 1.1nV/√Hz at 1kHz The OPA211 series of precision operational amplifiers achieves very low 1.1nV/ √Hz noise density • INPUT VOLTAGE NOISE: with a supply current of only 3.6mA. This series also 80nVPP (0.1Hz to 10Hz) offers rail-to-rail output swing, which maximizes • THD+N: –136dB (G = 1, f = 1kHz) dynamic range. • OFFSET VOLTAGE: 125µV (max) The extremely low voltage and low current noise, • OFFSET VOLTAGE DRIFT: 0.35µV/°C (typ) 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 loop filter amplifier in PLL applications. • UNITY-GAIN STABLE • GAIN BANDWIDTH PRODUCT: In precision data acquisition applications, the OPA211 series of op amps provides 700ns settling 80MHz (G = 100) time to 16-bit accuracy throughout 10V output swings. 45MHz (G = 1) This ac performance, combined with only 125 µV of • SLEW RATE: 27V/µs offset and 0.35 µV/°C of drift over temperature, makes • 16-BIT SETTLING: 700ns the OPA211 ideal for driving high-precision 16-bit analog-to-digital converters (ADCs) or buffering the • WIDE SUPPLY RANGE: output of high-resolution digital-to-analog converters ±2.25V to ±18V, +4.5V to +36V (DACs). • RAIL-TO-RAIL OUTPUT The OPA211 series is specified over a wide • OUTPUT CURRENT: 30mA dual-power supply range of ±2.25V to ±18V, or for • DFN-8 (3mm × 3mm), MSOP-8, AND SO-8 single-supply operation from +4.5V to +36V. The OPA211 is available in the small DFN-8 (3mm × 3mm), MSOP-8, and SO-8 packages. A dual version, • PLL LOOP FILTER the OPA2211, is available in the DFN-8 (3mm × • LOW-NOISE, LOW-POWER SIGNAL 3mm) or an SO-8 PowerPAD™ package. This series PROCESSING of op amps is specified from TA = –40°C to +125°C. • 16-BIT ADC DRIVERS • DAC OUTPUT AMPLIFIERS • ACTIVE FILTERS • LOW-NOISE INSTRUMENTATION AMPS • ULTRASOUND AMPLIFIERS • PROFESSIONAL AUDIO PREAMPLIFIERS • LOW-NOISE FREQUENCY SYNTHESIZERS • INFRARED DETECTOR AMPLIFIERS • HYDROPHONE AMPLIFIERS • GEOPHONE AMPLIFIERS • MEDICAL 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
