DESCRIPTION
The OPA4188 operational amplifier uses TI
proprietary auto-zeroing techniques to provide low
offset voltage (25 μV, max), and near zero-drift over
time and temperature. These miniature, high-
precision, low quiescent current amplifiers offer high
input impedance and rail-to-rail output swing within
15 mV of the rails. The input common-mode range
includes the negative rail. Either single or dual
supplies can be used in the range of +4.0 V to +36 V
(±2 V to ±18 V).
The quad version is available in SO-14 and TSSOP-
14 packages. All versions are specified for operation
from –40°C to +125°C.
