The LM732xx devices are rail-to-rail input and output amplifiers with wide operating voltages and high-output currents. The LM732xx family is efficient, achieving 35V/µs slew rate and 24MHz unity gain bandwidth while requiring only 1.35mA of supply current per op amp. The LM732xx device performance is fully specified for operation at 2.7V, ±5V, and ±15V.

The LM732xx devices are designed to drive unlimited capacitive loads without oscillations. Greater than rail-to-rail input common-mode voltage range with 90dB of common-mode rejection across this wide voltage range allows both high-side and low-side sensing. Most device parameters are insensitive to power supply voltage, and making the parts easier to use where supply voltage can vary, such as automotive electrical systems and battery powered equipment.
