DESCRIPTION
The OPA827 series of JFET operational amplifiers
combines outstanding dc precision with excellent ac
performance. It offers 100
μ
V of offset, very low drift
(1
μ
V/
°
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.
