T he ADT 7516/7517/7518 combines a 10-Bit T empera-
ture-to-Digital Converter, a 10-Bit Four Channel ADC
and a quad 12/10/8-Bit DAC respectively, in a 16-Lead
QSOP package. T his includes a bandgap temperature
sensor and a 10-bit ADC to monitor and digitize the tem-
perature reading to a resolution of 0.25

C. T he
ADT 7516/17/18 operates from a single +2.7 V to + 5.5 V
supply. T he input voltage range on the ADC channels has
a range of 0V to 2.25V and the input bandwidth is DC.
T he reference for the ADC channels is derived internally.
T he output voltage of the DAC ranges from 0 V to V
