® REF 200 REF200 REF 200 DUAL CURRENT SOURCE/CURRENT SINK FEATURES q COMPLETELY FLOATING: No Power Supply or Ground Connections q HIGH ACCURACY: 100µA ±0.
5% q LOW TEMPERATURE COEFFICIENT: ±25ppm/°C q WIDE VOLTAGE COMPLIANCE: 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 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, t...
