Design issues for translating a DC coupled unipolar input to a differential ADC at some V cm. It is a challenging task to provide an ADC interface circuit to satisfy both the source and the ADC when ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...

An electronic digital caliper is made to record the measurements to a computer with the use of RS232 interface. The design of the device can work not only with inexpensive calipers but also with ...

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...
