DESCRIPTION
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 (250nV_PP, 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.
