... PTAT R1 Figure 21. Simplified Schematic DEVICE POWER DISSIPATION CONSIDERATIONS The ADR293 is guaranteed to deliver load currents with an input voltage that ranges from 5 When this device is used in applications with large input voltages, care should be exercised to avoid exceeding the published specifications for maximum power dissipation or junction temperature that could result in premature device failure. The following formula should be used to calculate a device’ ...

... A PRECISION CURRENT SOURCE Many times in low power applications, the need arises for a precision current source that can operate on low supply voltages. As shown in Figure 24, the ADR293 is configured as a precision current source. The circuit configuration illustrated is a floating current source with a grounded load. The output voltage of the reference is bootstrapped across R the output current into the load ...
