LM7322 Datasheet | National Semiconductor

Description The LM7321/LM7322 are rail-to-rail input and output amplifiers with wide operating voltages and high output currents. The LM7321/LM7322 are efficient, achieving 18 V/µs slew rate and 20 MHz unity gain bandwidth while requiring only 1 m A of supply current per op amp. The LM7321/LM7322 per.. formance is fully specified for operation at 2.7V, ±5V and ±15V. The LM7321/LM7322 are designed to drive unlimited capacitive loads without oscillations. All LM7321 and LM7322 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 munications applications. Greater than rail-to-rail input mon mode voltage range with 50 d B of mon 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 m A) with minimal head- room from either rail (300 m V) 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. LM7322 is offered in a space saving 8-Pin MSOP package. The LM7321 is offered in small SOT23-5 package, which makes it easy to place this part close to sensors for better circuit performance.
