External Configuration
Description
Configuration 1
46
TS83102G0B
When this function is active, the ADC outputs only 1 out of 32 bits of data, resulting in a data
rate 32 times slower than the clock rate.
Note:
Because of the use of one internal diode-mounted transistor (used for junction temperature
monitoring), you have to implement external head-to-tail protection diodes so as to avoid
potential reverse current flows, which can damage the internal diode component.
Two external configurations are possible:
•
•
This external configuration allows you to apply the requested levels to activate output data
decimation (V
explains why 7 protection diodes are needed in the other direction, as shown in Figure 51).

ature Monitoring Function and Decimation Mode

Configuration 1: allows both junction temperature monitoring and output data decimation.
Configuration 2: allows junction temperature monitoring only.
The ADC decimation test mode is different from the pattern generator function, which is used to
check the ADC’s outputs.
