... Industrial Process Control Systems Hard Disk Drives Automotive GENERAL DESCRIPTION The ADR380 and ADR381 are precision 2.048 V and 2.500 V band gap voltage references featuring high accuracy, high stabil- ity, and low-power consumption in a tiny footprint. Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature ...

... R58 R49 R48 R61 Figure 2. Stacking Voltage References with the GND ADR380/ADR381 Two ADR380s or ADR381s are used; the outputs of the indi- vidual references are simply cascaded to reduce the supply current. Such configuration provides two output voltages— V and V OUT1 V is the sum of this voltage and the terminal voltage of U2. ...

... Many times in low power applications, the need arises for a pre- cision current source that can operate on low supply voltages. As shown in Figure 4, the ADR380/ADR381 can be configured as a precision current source. The circuit configuration illustrated is a floating current source with a grounded load. The reference’s output voltage is bootstrapped across R the output current into the load ...
