LM7321MFE/NOPB General Description

The LM7321MFE/NOPB is a precision, low-power operational amplifier (op-amp) manufactured by Texas Instruments. It features a single operational amplifier with a rail-to-rail output swing and a low input offset voltage. This op-amp is designed for applications requiring low input offset voltage, low input bias current, and high input impedance. With a wide supply voltage range from 2.7V to 12V and a low quiescent current consumption of 900µA (typical), it's suitable for battery-powered devices and low-power applications. The LM7321 provides high performance in terms of slew rate and bandwidth, making it suitable for precision instrumentation and sensor signal conditioning. It comes in a small SOT-23 package, making it space-efficient and suitable for compact designs. The device is also unity-gain stable and has excellent temperature stability, ensuring reliable performance across varying operating conditions
