The OPA827 series of JFET operational amplifiers combine outstanding dc precision with excellent ac performance. These amplifiers offer low offset voltage (150µV, max), very low drift over temperature (0.5µV/°C, typ), low bias current (3pA, typ), and very low 0.1Hz to 10Hz noise (250nVPP, typ). The device operates over a wide supply voltage range, ±4V to ±18V on a low supply current (4.8mA/Ch, typ).
Excellent ac characteristics, such as a 22MHz gain bandwidth product (GBW), a slew rate of 28V/µs, and precision dc characteristics make the OPA827 series well-suited for a wide range of applications including 16-bit to 18-bit mixed signal systems, transimpedance (I/V-conversion) amplifiers, filters, precision ±10V front ends, and professional audio applications.
The OPA827 is available in both SO-8 and MSOP-8 surface-mount packages, and is specified from –40°C to +125°C.
