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 18-V/µs slew rate and
20-MHz unity gain bandwidth while requiring only 1 mA of supply current per op amp. The LM732xx
device performance is fully specified for operation at 2.7 V, ±5 V and ±15 V.
The LM732xx devices are designed to drive unlimited capacitive loads without
oscillations. All LM7321x and LM7322x parts are tested at 40°C, 125°C, and 25°C, with modern
automatic test equipment. High performance from 40°C to 125°C, detailed specifications, and
extensive testing makes them suitable for industrial, automotive, and communications
Greater than rail-to-rail input common-mode voltage range with 50 dB 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 this makes the parts easier to use where
supply voltage may vary, such as automotive electrical systems and battery powered equipment. These
amplifiers have true rail-to-rail output and can supply a respectable amount of current (15 mA)
with minimal head- room from either rail (300 mV) at low distortion (0.05% THD+Noise).
There are several package options for each part. Standard SOIC versions of both parts
make upgrading existing designs easy. LM7322x are offered in a space-saving 8-Pin VSSOP package.
The LM7321x are offered in small SOT-23 package, which makes it easy to place this part close to
sensors for better circuit performance.
