DESCRIPTION
The OPA2188 operational amplifier uses TI
proprietary auto-zeroing techniques to provide low
offset voltage (25 μV, max), and near zero-drift over
time and temperature. This miniature, high-precision,
low quiescent current amplifier offers 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 OPA2188 is available in MSOP-8 and SO-8
packages. The device is specified for operation from
–40°C to +105°C.
