Overview
The LMV822MMX/NOPB is a dual operational amplifier from Texas Instruments, designed for low voltage and low power applications. This device is part of the LMV821/LMV822/LMV824 family, which offers a balance of performance and economy. The LMV822MMX/NOPB features a 5 MHz unity-gain frequency and a specified 1.4 V/μs slew rate, making it suitable for a variety of analog signal processing tasks. It operates with a quiescent current of only 220 μA per amplifier at 2.7 V, and it provides rail-to-rail output swing into heavy loads, such as 600 Ω.
