Overview
The LMV710-N, LMV711-N, and LMV715-N operational amplifiers, including the LMV710M5X/NOPB, are BiCMOS operational amplifiers designed by Texas Instruments. These devices feature a CMOS input stage, providing high performance and low power consumption. They are ideal for power-sensitive applications, such as cellular phones, pagers, palm computers, and other battery-powered portable electronics. The LMV710-N series offers rail-to-rail input and output, high current drive, and a bandwidth of 5 MHz with a slew rate of 5 V/µs, making them versatile for various analog signal processing tasks.
