3 Description
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 applications.
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).

5 Description continued
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.
