LMP2232 Dual
Micropower, 1.6V, Precision, Operational Amplifier with
CMOS Input
General Description
The LMP2232 is a dual micropower precision amplifier de-
signed for battery powered applications. The 1.6V to 5.5V
operating supply voltage range and quiescent power con-
sumption of only 26 μW extend the battery life in portable
systems. The LMP2232 is part of the LMP
family. The high impedance CMOS input makes it ideal for
instrumentation and other sensor interface applications.
The LMP2232 has a maximum offset voltage of 150 μV and
maximum offset voltage drift of only 0.5 μV/°C along with low
bias current of only ±20 fA. These precise specifications make
the LMP2232 a great choice for maintaining system accuracy
and long term stability.
The LMP2232 has a rail-to-rail output that swings 15 mV from
the supply voltage, which increases system dynamic range.
The common mode input voltage range extends 200 mV be-
low the negative supply, thus the LMP2232 is ideal for ground
sensing in single supply applications.
The LMP2232 is offered in 8-pin SOIC and MSOP packages.
The LMP2231 is the single version of this product and the
LMP2234 is the quad version of this product. Both of these
products are available on National Semiconductor's website.
