NCT7290 Datasheet, PDF (1/33 Pages) ON Semiconductor – Internal Temp Sensor

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 I²C
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.
