Low loss instrumentation amplifier
Source: InternetPublisher:sigma Keywords: Power battery circuit Updated: 2021/04/14
Instrumentation amplifiers generally require one or two 9V resistor batteries. Due to the serious current loss, these instruments need to be turned off when not in use. The working battery of the meter introduced here is two 1.5V flash batteries, and the power loss of the meter is very low, so there is no need for any on/off switch.
