Reference

+1.23 V
Voltage Reference Input/Output.
An internal voltage source of +1.2
Volts (nominal) is applied to the V
REF
terminal. This is the reference for
all three D/A converters of the TMC2081. Decoupling V
REF
to A
GND
with a 0.1
m
F ceramic capacitor is recommended. This pin may also be
used as an input for an external voltage reference source.
Current-Setting Resistor.
Full-scale output current of the TMC2081
is determined by the value of the resistor connected between R
REF
and A
GND
. Varying this resistor will vary the “white” output level for all
three D/A converters. The TMC2081 is not designed for operation with
an external current reference.
Compensation Capacitor.
A 0.1
m
F ceramic capacitor is connected
between the COMP and V
DDA
at pin 70 or 71.

Analog Power Supply.
The TMC2081 operates from a single +5V
supply. All power pins must be connected. V

must be
derived from a common power supply.
Digital Power Supply.
The TMC2081 operates from a single +5V
supply. All power pins must be connected. V

and V
DD
must be
derived from a common power supply.
Analog Ground.
All ground pins must be connected.
Digital Ground.
All ground pins must be connected.
