OPERATIONAL AMPLIFIER

FEATURES

DESCRIPTION

•

INPUT VOLTAGE NOISE DENSITY:

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

(1.5µV/°C, typ), low bias current (15pA, 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).

INPUT VOLTAGE NOISE:

xx0.1Hz to 10Hz: 250nV_PP

•

INPUT BIAS CURRENT: 15pA

INPUT OFFSET VOLTAGE: 150µV (max)

INPUT OFFSET DRIFT: 1.5µV/°C

GAIN BANDWIDTH: 22MHz

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⁽¹⁾

surface-mount packages, and is specified from –40°C

to +125°C.

SLEW RATE: 28V/µs

QUIESCENT CURRENT: 4.8mA/Ch

WIDE SUPPLY RANGE: ±4V to ±18V

PACKAGES: SO-8 and MSOP-8⁽¹⁾
