NEGATIVE PRECISION REFERENCE WITHOUT
PRECISION RESISTORS
A negative reference is easily generated by adding an op amp,
A1, and is configured as shown in Figure 36. V
OUT
is at virtual
ground and, therefore, the negative reference can be taken
directly from the output of the op amp. The op amp must be
dual-supply, low offset, and rail-to-rail if the negative supply
voltage is close to the reference output.

PRECISION CURRENT SOURCE
In low power applications, the need can arise for a precision
current source that can operate on low supply voltages. The
ADR130 can be configured as a precision current source (see
Figure 37). The circuit configuration shown is a floating current
source with a grounded load. The reference 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 supply current,
typically 85 μA, to approximately 4 mA.
