    Analog isolator circuit design

    I am studying the schematics of an analog isolator with variable gain (SIM 984 from SRS0, the isolator is bipolar and can handle positive and negative voltages. In the isolation part of the schematics (see picture below), the author uses two voltage references circled in red. Having read the...

    Detect-if-Connected circuit for DSLR -low voltage, low current.

    Hello, I have a DSLR camera which will have a long, wired remote trigger controlled by a microcontroller (I'm using an STM32 Nucleo). My goal is to: A. Detect that the remote trigger between the camera and MCU is plugged in, and illuminate an LED. B. Have the MCU trigger the shutter (take a...
