说明

The LPV511 is a micropower operational amplifier that operates from a voltage supply range as wide as 2.7 V to 12 V with ensured specifications at 3 V, 5 V, and 12 V. The ultra-low power LPV511 exhibits an excellent speed to power ratio, drawing only 880 nA of supply current with a bandwidth of 27 kHz. These specifications make the LPV511 an ideal choice for battery-powered systems that require long life through low supply current, such as instrumentation, sensor conditioning and battery current monitoring.

The LPV511 has an input range that includes both supply rails for ground and high-side battery sensing applications. The LPV511 output swings within 100 mV of either rail to maximize the signal’s dynamic range in low supply applications. In addition, the output is capable of sourcing 650 µA of current when powered by a 12-V battery.

The LPV511 is fabricated on TI’s advanced VIP50C process.

The LPV511 is available in the space-saving SC70 package, which makes it ideal for portable electronics with area-constrained PC boards.
