LM7332 Dual Rail-to-Rail Input/Output
30V, Wide Voltage Range, High Output Operational
Amplifier
General Description
The LM7332 is a dual rail-to-rail input and output amplifier with
a wide operating temperature range (−40°C to +125°C) which
meets the needs of automotive, industrial and power supply
applications. The LM7332 has the output current of 100 mA
which is higher than that of most monolithic op amps. Circuit
designs with high output current requirements often need to
use discrete transistors because many op amps have low
current output. The LM7332 has enough current output to
drive many loads directly, saving the cost and space of the
discrete transistors.
The exceptionally wide operating supply voltage range of
2.5V to 32V alleviates any concerns over functionality under
extreme conditions and offers flexibility of use in a multitude
of applications. Most of this device's parameters are insensi-
tive to power supply variations; this design enhancement is
another step in simplifying usage. Greater than rail-to-rail in-
put common mode voltage range allows operation in many
applications, including high side and low side sensing, without
exceeding the input range.
The LM7332 can drive unlimited capacitive loads without os-
cillations.
The LM7332 is offered in the 8-pin MSOP and SOIC pack-
ages.
