Overview
The LMV712MM/NOPB is a high-performance, low power, low noise, dual operational amplifier from Texas Instruments. This BiCMOS operational amplifier is designed for applications requiring rail-to-rail inputs combined with high speed and low noise. It is available in various packages, including 10-pin DSBGA, 10-pin WSON, and 10-pin VSSOP, making it suitable for space-constrained and battery-operated portable electronics.
The device features a gain-bandwidth product of 5 MHz and a slew rate of 5 V/µs, ensuring high-speed operation. It also offers low input offset voltage and high common mode rejection ratio, making it ideal for precision applications. The LMV712MM/NOPB is ensured to operate over a wide supply voltage range from 2.7 V to 5.5 V and has a temperature range of –40°C to 125°C for the automotive-grade version (LMV712-N-Q1).
