OPERATIONAL AMPLIFIER

FEATURES

DESCRIPTION

•

OFFSET: 250μV (max)

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.

DRIFT: 1μV/°C

LOW NOISE: 4.5nV/√Hz at 1kHz

BANDWIDTH: 18MHz

SLEW RATE: 22V/μs

BIAS CURRENT: 3pA

QUIESCENT CURRENT: 4.5mA/Ch

WIDE SUPPLY RANGE: ±4V to ±18V

SINGLE PACKAGES: MSOP-8, SO-8

DUAL PACKAGES: SO-8 PowerPAD

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-

18-bit

data

acquisition

systems,

transimpedance (I/V-conversion) amplifiers, filters,

precision ±10V front ends, and professional audio

applications.

APPLICATIONS

•

PRECISION ±10V INPUT FRONT-ENDS

TRANSIMPEDANCE AMPLIFIERS

INTEGRATORS

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 SO-8 PowerPAD for increased power

dissipation capability. All versions are specified from

–40°C to +125°C.
