Overview
The LMV822MM/NOPB is a dual operational amplifier (op-amp) produced by Texas Instruments. It is part of the LMV821/LMV822/LMV824 family, which offers high performance and economy in low-voltage, low-power systems. This device features a 5 MHz unity-gain frequency at a 2.7 V supply and a slew rate of 1.4 V/μs. The LMV822MM/NOPB is particularly noted for its rail-to-rail output (RRO) swing and its ability to drive large capacitive loads, making it suitable for a wide range of applications at an economical price.
