Analog mV Switch for Digital Meters
Let us assume you have to Measure Amps and Volts in four independent circuits. This becomes a Multi Channel Voltmeter and Ammeter. This circuit uses a 4052 as a DC Analog Multiplexer, the inputs...

Digital to Analog Converter with uC Watchdog
This is the continuation of the earlier post. Part of 80C39 based Process Controller. In this schematic you can see the Watchdog and D/A Converter. 80C39 and MCS48 based Process Controller is the main...
Mixed Signal Grounding Method
How do we interface Analog and Digital Blocks. The earlier post explains ground connections that are radiating from supply but does not show Analog and Digital Blocks Interface.
LM3914 Circuit Ground Connections
I am about to build the circuit that you have here: – Millivolt Meter – Bargraph I am pretty sure that I understand all of it, except for the symbols that you have at...
