General-Purpose Current Source
Many times in low power applications, the need arises for a
precision current source that can operate on low supply
voltages. The ADR36x can be configured as a precision current
source (see Figure 36). The circuit configuration illustrated is a
floating current source with a grounded load. The reference’s
output voltage is bootstrapped across R
SET
, which sets the output
current into the load. With this configuration, circuit precision
is maintained for load currents ranging from the reference’s
supply current, typically 150 μA, to approximately 5 mA.

Trim Terminal
The ADR36x trim terminal can be used to adjust the output
voltage over a nominal voltage. This feature allows a system
designer to trim system errors by setting the reference to a
voltage other than the standard voltage option. Resistor R1 is
used for fine adjustment and can be omitted if desired. The
resistor values should be carefully chosen to ensure that the
maximum current drive of the part is not exceeded.
