MTA2188 低噪声、零漂移、， 精密运算放大器

The MTA0188/2188 operational amplifiers use
proprietary auto-zeroing techniques to provide low
offset voltage (25-μ V 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.
The input common-mode range includes the
negative rail.
Either single or dual supplies can be used in the
range from 4 V to 36 V (±2 V to ±18 V). This
amplifier is available in the MicroSIZE SOT23-5,
MSOP-8, and SO-8 packages. All versions are
specified for operation from –55°C to +125°C.
