Preliminary Product Information -

Confidential

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

I²C interface which is compatible with industry standard

protocols or a 4 wire SPI interface. Both interfaces are

available on this part. Through these interfaces the

NCT7290s internal registers may be accessed. These

registers allow the user to read the current temperature and

input voltages, change the configuration settings, adjust

each channels limits and set set the output DAC voltages on

each of the 12 channels available.

The NCT7290 is available in a 56-lead QFN (8x8x0.5 mm)

package and operates over a supply range of 5.0 V ±10%

(digital supply range of 3.0 V to 5.5 V) and temperature

range of –55 to +125°C. This makes the NCT7290 ideal for

a wide variety of applications ranging from cellular base

stations to servers and industrial controls.
