DESCRIPTION
The OPA827 series of JFET operational amplifiers
combines outstanding dc precision with excellent ac
performance. It offers 100渭V of offset, very low drift
(1渭V/擄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
鹵4V
to
鹵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/渭s 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
鹵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 SO-8 PowerPAD for increased power
dissipation capability. All versions are specified from
鈥?0擄C to +125擄C.
