V3.01

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.

1 For the digital supply voltage VDD it is not allowed to use a voltage above VDDA + 0.3 V. This condition must also be observed during

the ramp-up time of the supply voltages.

2 The resistor influences the TOLIFSR of the reference current for the signal conversion directly. Therefore the temperature coefficient of

the resistance plays an important role. The smaller the temperature coefficient and the resistor value tolerance (1 % is better than 5 %,

etc.), the more accurate the result is of the conversion process.
