SBOS376E – NOVEMBER 2006 – REVISED SEPTEMBER 2008 Low-Noise, High-Precision, JFET-Input OPERATIONAL AMPLIFIER 2 • INPUT VOLTAGE NOISE DENSITY: The OPA827 series of JFET operational amplifiers xx 4nV/ √Hz at 1kHz combine outstanding dc precision with excellent ac performance. These amplifiers offer low offset voltage • INPUT VOLTAGE NOISE: (150 µV, max), very low drift over temperature xx 0.1Hz to 10Hz: 250nVPP (1.5 µV/°C, typ), low bias current (15pA, typ), and very • INPUT BIAS CURRENT: 15pA low 0.1Hz to 10Hz noise (250nVPP, typ). The device • INPUT OFFSET VOLTAGE: 150µV (max) operates over a wide supply voltage range, ±4V to ±18V on a low supply current (4.8mA/Ch, typ). • INPUT OFFSET DRIFT: 1.5µV/°C • GAIN BANDWIDTH: 22MHz Excellent ac characteristics, such as a 22MHz gain bandwidth product (GBW), a slew rate of 28V/ µs, and • SLEW RATE: 28V/µs precision dc characteristics make the OPA827 series • QUIESCENT CURRENT: 4.8mA/Ch well-suited for a wide range of applications including • WIDE SUPPLY RANGE: ±4V to ±18V 16-bit to 18-bit mixed signal systems, transimpedance (I/V-conversion) amplifiers, filters, precision ±10V • PACKAGES: SO-8 and MSOP-8(1) front ends, and professional audio applications. (1) MSOP-8 (DGK) package is product preview. The OPA827 is available in both SO-8 and MSOP-8(1) surface-mount packages, and is specified from –40°C to +125°C. • ADC DRIVERS • DAC OUTPUT BUFFERS • TEST EQUIPMENT • MEDICAL EQUIPMENT • PLL FILTERS • SEISMIC APPLICATIONS • TRANSIMPEDANCE AMPLIFIERS • INTEGRATORS • ACTIVE FILTERS 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 All trademarks are the property of their respective owners.
