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).
