Interfacing TLV5620 With Arduino

Tuesday, October 15th, 2013

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),...
