NCT7290 16 Channel ADC, 12 Channel DAC, Internal Temp Sensor with I2C & SPI Interface The NCT7290 is a serially programmable voltage and temperature monitor.

It can monitor its on chip temperature via its local sensor, a remotely connected diode and 16 analog inputs.

Two 12 bit DACs allow for voltage control on 12 pins.

Eight GPIO pins allow digital control and monitoring.

An ALERT output is also available to signal out-of-limit conditions.

Communication with the NCT7290 is accomplished via an
