The LM7321/LM7322 is a high-performance operational amplifier with a wide operating voltage range, high output current, and the ability to drive unlimited capacitive loads. It offers an 18 V/µs slew rate and a 20 MHz unity gain bandwidth while requiring only 1 mA of supply current per op amp.
The LM7321 (single) and LM7322 (dual) are rail‑to‑rail input and output operational amplifiers offering a wide supply voltage range, high output current, and low distortion. They are designed for industrial, automotive, and communications applications and can drive unlimited capacitive loads without oscillation.
The devices are offered in several packages, including 5‑Pin SOT‑23, 8‑Pin MSOP, and 8‑Pin SOIC, with ordering information and typical performance curves provided. Additional product details and design tools are available on the National Semiconductor website.
