Overview
The LPV511MG/NOPB is a micropower operational amplifier produced by Texas Instruments. It operates from a wide supply voltage range of 2.7 V to 12 V, ensuring specifications at 3 V, 5 V, and 12 V. This ultra-low power amplifier is designed for battery-powered systems, offering an excellent speed to power ratio. It draws only 880 nA of supply current while maintaining a bandwidth of 27 kHz, making it ideal for applications requiring long battery life, such as instrumentation, sensor conditioning, and battery current monitoring. The LPV511 is fabricated on TI's advanced VIP50C process and is available in the space-saving SC70 package, suitable for portable electronics with area-constrained PC boards.
