DAC
4.2
The TPMC533 provides up to sixteen analog output channels (DAC Channels) available at the Front I/O
Connector.
Analog Devices AD5754R are used for the analog outputs. Each AD5754R provides four 16Bit single-ended
DAC channels (DAC Channels A-D).
•
The TPMC533-10R order option provides four AD5754R (DAC1, DAC2, DAC3 & DAC4)

Table 4-3 : DAC Electrical Interface
The TPMC533 provides an “Automatic Channel Power-Down” feature for the DACs.
In case of a DAC Channel overcurrent condition, the DAC Channel is powered down and its output is
clamped to ground with a resistance of ~4 k
Ω. This condition is indicated by the
DACx_OCx bit set to ‘1’ and
the DACx_PUx set to ‘0’ in the corresponding DAC Status Register.
The channel can be powered up again by setting the DACx_PU_x bit in the corresponding DAC
Configuration Register back to ‘1’ after the overload condition is removed.
