DESCRIPTION

The OPA827 series of JFET operational amplifiers

combines outstanding dc precision with excellent ac

performance. It offers 100

µV of offset, very low drift

(1

µV/°C) over temperature, low bias currents, and very low

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.
