Product Summary
The ref200ap is an 8-Pin Plastic DIP, dual current source/current sink. It combines three circuit building-blocks on a single monolithic chip—two 100μA current sources and a current mirror. The sections are dielectrically isolated, making them completely independent. Also, since the current sources are twoterminal 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 50μA, 100μA, 200μA, 300μA or 400μA. External circuitry can be used to obtain virtually any current. These and many other circuit techniques are shown in the applications section of this data sheet. The ref200ap is available in plastic 8-pin mini-DIP and SOIC packages. The ref200ap can be used in sensor excitation, biasing circuitry, offsetting current loops, low voltage references, charge-pump circuitry, and hybrid microcircuits.
