3 Description
The OPA180-Q1 and OPA2180-Q1 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 single-channel and dual-channel versions are
offered in VSSOP-8 packages.. All versions are
specified for operation from –40°C to +105°C.
