The REF200 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.
The sections can be pin-strapped for currents of 50 µA, 100 µA, 200 µA, 300 µA, or 400 µA. External circuitry can obtain virtually any current. These and many other circuit techniques are shown in the Application Information section of this data sheet.
The REF200 is available in an SOIC package.
