3 Description
The LM7332 device is a dual rail-to-rail input and
output amplifier with a wide operating temperature
range (−40°C to +125°C) that meets the needs of
automotive, industrial, and power supply applications.
The LM7332 has an output current of 100 mA, which
is higher than that of most monolithic operational
amplifiers. Circuit designs with high output current
requirements often require discrete transistors
because many operational amplifiers 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 2.5 V to 32 V alleviates any concerns over functionality under extreme conditions and offers
flexibility of use in a multitude of applications. Most
parameters of this device are insensitive to power
supply variations; this design enhancement is another
step in simplifying usage. Greater than rail-to-rail
input 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 oscillations.
The LM7332 is offered in the 8-pin VSSOP and SOIC
packages.
