DESCRIPTION
The OPA827 series of JFET operational amplifiers
combines outstanding dc precision with excellent ac
performance. It offers 100µV of offset, very low drift
(1µV/°C) over temperature, low bias currents, and very low
flicker noise of 400nV_PP (0.1Hz to 10Hz). It operates over
a very wide supply voltage range of ±4V to ±18V on a low
4.5mA supply current. A dual version is also available for
the OPA827 family.
Excellent ac characteristics, such as 18MHz gain
bandwidth (GBW) and 22V/µs slew rate, and precision dc
characteristics make the OPA827 series well-suited for a
wide range of applications such as 16- to 18-bit data
acquisition systems, transimpedance (I/V−conversion)
amplifiers, filters, precision ±10V front-ends, and
professional audio applications.
The single version (OPA827) is available in both MSOP-8
and standard SO-8 surface-mount packages. The dual
version (OPA2827) is available in the small TSSOP-8 and
in the standard SO-8 packages. All versions are specified
from −40°C to +125°C.
