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.
