TSEV83102G0B - Evaluation Board User Guide

2166B–BDC–04/03

For Revision B, the V

DIODE

 characteristic corresponds to a single diode characteristic

over temperature, thus starting at 0.9V, as illustrated in Figure 4-4, which is only an
interpolated V

DIODE

 characteristic (to be confirmed by future measurements).

This modification in Revision B devices implies the modification of the processing of the
V

DIODE

 characteristic if any but above all, it allows the user to implement a digital temper-

ature sensor to be interfaced with the ASIC (DSP, FPGA, etc...) loading the ADC.

Figure 4-4.  Diode Pin Implementation in Test Mode

A typical configuration with a standard digital temperature sensor is depicted in
Figure 4-5.
