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.
