NCT7290

16 Channel ADC,

12 Channel DAC,

Internal Temp Sensor

with I²C & SPI Interface

http://onsemi.com

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 I C

QFN−56

CASE 485BK

interface which is compatible with industry standard protocols or a 4

wire SPI interface. Both interfaces are available on this device.

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 (8 × 8 × 0.5 mm)

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

supply range of 3 V to 3.6 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.
