SBVS020C September 2000 – February 2020 REF200
The REF200 device combines three circuit building-blocks on a single monolithic chip—two 100-µA current sources and a current mirror. The sections are dielectrically isolated, making them completely independent. Also, because the current sources are two terminal devices, they can be used equally well as current sinks. The performance of each section is individually measured and laser-trimmed to achieve high accuracy at low cost.
