LM7322 (LM7321 / LM7322) High Output Current and Unlimited Capacitive Load Operational Amplifier

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 mA of supply current per op amp. The LM7321/LM7322 perwww.DataSheet4U.com formance is fully specified for operation at 2.7V, ±.
