Power-saving use of the amplifier's disable pin

摘要

Battery-operated applications are increasingly popular in the IoT era. Luckily, there doesn't have to be a trade-off between power saving and accuracy. Some operational amplifiers have disable pins and, when used correctly, they can yield up to 99% power savings without compromising accuracy.The disable pin is primarily used in static operation (standby mode). In this mode, all ICs are switched to a state of low power consumption, without the device being used for signal processing, which slashes the power consumption by several orders of magnitude.
