National Semiconductor LMV551 Data Sheet
Summary
The LMV551/LMV552/LMV554 are high-performance, micropower operational amplifiers featuring up to 3 MHz bandwidth and rail-to-rail output. Ideal for low power applications, the manual provides detailed electrical characteristics, temperature ratings, and technical specifications necessary for designers. Designed with a wide operating voltage range (2.7V–5.5V) and robust performance down to -40°C, these op-amps are specifically suited for demanding environments like automotive systems, portable instrumentation, active filters, and battery-powered sensor applications.
