V3.11

2 ELECTRICAL CHARACTERISTICS

2.1 Absolute Maximum Ratings

Violations of absolute maximum conditions are not allowed under any circumstances; otherwise the IC can

be destroyed.

All voltages are referenced to VSSA = VSS = 0 V.

3 For the Digital Supply Voltage VDD it is not allowed to use a voltage above VDDA+0.3 V. This condition must be also complied during

the ramp-up phase of the supply voltages.

4 The resistor directly influences the generating of the reference current for the signal conversion. Therefore, the temperature coefficient

of resistance has an important role. The smaller the temperature coefficient and the resistor value tolerance (1% better than 5%, etc.)

result the more accurate the result of the converting.

5 The smaller the better - the result depend on the sum of all TKs of the full sensor system (photo diode, REXT, converter, …)
