Digital-to-analog converters (DACs) come in many bit resolutions and sampling speeds. Outputs from lower-speed DACs are often single-ended and have either a voltage or a current output. Most highspeed DACs are designed with complementary outputs that either source or sink current. This article, Part 1 of a three-part series, discusses the interface between a current-sinking DAC and an op amp.
