REF200 Datasheet | Burr-Brown

® REF 200 DUAL CURRENT SOURCE/CURRENT SINK Features q PLETELY FLOATING: No Power Supply or Ground Connections q HIGH ACCURACY: 100µA ±0.5% q LOW TEMPERATURE COEFFICIENT: ±25ppm/°C q WIDE VOLTAGE PLIANCE: 2.5V to 40V q ALSO INCLUDES CURRENT MIRROR APPLICATIONS q SENSOR EXCITATION q BIASING CIRCUITRY q OFFSETTING CURRENT LOOPS q LOW VOLTAGE REFERENCES q CHARGE-PUMP CIRCUITRY q HYBRID MICROCIRCUITS DESCRIPTION The REF200 bines three circuit building-blocks on a single monolithic chip- two 100µA current sources and a current mirror. The sections are dielectrically isolated, making them pletely independent. Also, since the current sources are twoterminal devices,...
