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 (more…)

How do we interface Analog and Digital Blocks. The earlier post explains ground connections that are radiating from supply but does not (more…)

I am about to build the circuit that you have here: – Millivolt Meter – Bargraph I am pretty sure that I (more…)

This is a R-2R Digital to Analog Converter, It converts a byte (8 bit) to a analog value. It has 256 levels (more…)

A, B, and C are the Digital Control for x, y and z input and output pairs.The voltage at Vinx is stored (more…)

This Circuit is a simple Analog to Digital Interface with a capability of 10 to 12 bits resolution. 10 bits means 1024 (more…)
