DESCRIPTION
The OPA192 family ⁽¹⁾ (OPA192, OPA2192, and
OPA4192) is a new generation of 36-V, e-trim
operational amplifiers. These devices offer
outstanding dc precision and ac performance,
including rail-to-rail input/output, low offset (±5 µV,
typ), low offset drift (±0.2 µV/°C, typ), and 10MHz
bandwidth. Unique features such as differential input-
voltage range to the supply rail, high output current
and high capacitive load drive of up to 1 nF, and high
slew rate make the OPA192 a robust, high-
performance operational amplifier for high-voltage
industrial applications. The OPA192 family of op
amps is available in standard packages and is
specified from –40°C to +125°C.
