This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

Simple DACs realized by lowpassfiltering microcontroller-generatedpulse-width-modulated(PWM) signals have a response that istypically a tenth of the PWM frequency.This Design Idea is a novel ...

One useful dynamic application of μCs is as analog-to-digital converters (ADCs). ADCs over the years have gone from complete DVMs as instruments to embedded subsystems, to a few components. This ...

We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and download a compendium of analog sub-circuits. Individual circuits can be ...
