The OPA827 series of JFET
operational amplifiers combine outstanding DC precision with excellent AC performance. These
amplifiers offer low offset voltage (150 µV, maximum), very low drift over temperature (0.5 µV/°C,
typical), low-bias current (3 pA, typical), and very low 0.1-Hz to 10-Hz noise (250
nVPP, typical). The device operates over a wide supply voltage range, ±4 V
to ±18 V on a low supply current (4.8 mA/Ch, typical).
Excellent AC characteristics, such as a 22-MHz gain bandwidth product (GBW), a slew rate
of 28 V/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 ±10-V front ends, and professional audio applications.
The OPA827 is available in both 8-pin SOIC and 8-pin VSSOP surface-mount packages, and is
specified from –40°C to 125°C.
