The ADT75181 combines a 10-bit temperature-to-digital converter, a 10-bit 4-channel ADC, and a quad 8-bit DAC, in a 16-lead QSOP package. The part also includes a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25C. The ADT7518 operates from a single 2.7 V to 5.5 V supply. The input voltage range on the ADC channels is 0 V to 2.25 V, and the input bandwidth is dc. The reference for the ADC channels is derived internally. The output voltage of the DAC ranges from 0 V to VDD, with an output voltage settling time of 7 ms typical.
