3 Description
The OPA4188 operational amplifier uses TI
proprietary auto-zeroing techniques to provide low
offset voltage (25 μV, maximum), 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, making them ideal for industrial
applications. The input common-mode range includes
the negative rail. Either single or dual supplies can be
used in the range of 4 V to 36 V (±2 V to ±18 V).
The quad version is available in 14-pin SOIC and 14-
pin TSSOP packages. All versions are specified for
operation from –40°C to 125°C.
