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 400nVPP (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.
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: TSSOP-8, SO-8
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)

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.
