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 milliamp current per op-amp supply. The LM7321/LM7322 performance is fully specified to operate at 2.7V, ± 5V, and ± 15V.
The LM7321/LM7322 are infinitely capacitive load drives without oscillation. All LM7321 and LM7322 components are tested at -40°C, 125°C and 25°C, with modern automated test equipment. The high performance of detailed specifications and extensive testing from -40°C to 125°C makes them suitable for use in industrial, automotive and communication applications.
The common mode suppression of the rail-to-rail common mode input voltage range of 50 dB spans the wide voltage range, enabling high and low side detection. Most equipment parameters are not sensitive to power supply voltage, which makes it easier to use power supply voltages that can vary in such as automotive electrical systems and battery-powered equipment, parts. These amplifiers have true rail-to-rail outputs and can deliver from a respectable current (15 mA) with the smallest head room, both at low distortion (0.05% THD + noise) rail (300 mV). Each section has a variety of package options. The standard SOIC package version in two parts makes it easy to upgrade existing designs. The LM7322 is available in a space-saving 8-pin MSOP package. The LM7321 is available in a small SOT23-5 package, which makes it easy to put this part close to the sensor for better circuit performance.
