3 Description
The OPA180, OPA2180 and OPA4180 operational
amplifiers (op amps) use TI's proprietary zero-drift
techniques to simultaneously provide low offset
voltage (75 μV), and near zero-drift over time and
temperature. These miniature, high-precision, low-
quiescent-current op amps offer high input
impedance and rail-to-rail output swing within 18 mV
of the rails. The input common-mode range includes
the negative rail. Single- or dual-supplies ranging
from 4 V to 36 V (±2 V to ±18 V) can be used.
The dual-channel version is offered in VSSOP-8
packages and SOIC-8 packages. The quad-channel
version is offered in SOIC-14 and TSSOP-14
packages. The single and quad package offerings
(OPA180 and OPA4180) are specified from –40°C to
+125°C, and the dual package (OPA2180) is
specified from –40°C to +105°C.
