Extending DAC resolution using digital potentiometer

Kerry Wong writes: One way to extend the resolution of a digital-to-analog converter (DAC) is by employing a sigma-delta converter in software. The main disadvantage of such approach is the slow speed. Alternatively, we can use some extra hardware to extend the usable resolution of a DAC. In this post, I will illustrate one such […]

Interfacing TLV5620 With Arduino

Kerry Wong posted an article on interfacing the TLV5620 with an Arduino: TI’s TLV5620 is a budget 4-channel 8-bit DAC. While it is designed primarily for running with a power supply between 3V and 3.6V, it can be powered by 5V as well given its wide supply voltage range. With a TL431 voltage reference (2.5V), the DAC output can cover […]
