NCD9812 Multichannel ADC, DACs and Temperature Sensors 2 with I C & SPI Interface Introduction The NCD9812 is a serially programmable voltage and temperature www.onsemi.com monitor. It can monitor its on chip temperature via its local sensor, and two remotely connected diodes and also voltage, via 16 analog inputs. MARKING Four of these analog inputs can be programmed to be differential type DIAGRAMS inputs. By default, they are all single ended inputs. Multiple 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 outoflimit conditions. TQFP64 EP, 10x10 NCD9812 2 Communication with the NCD9812 is accomplished via an I C CASE 136AC AWLYYWWG interface which is compatible with industry standard protocols or a 4 A = Assembly Location wire SPI interface. Both interfaces are available on this part. Through WL = Wafer Lot these interfaces the NCD9812s internal registers may be accessed. YY = Year These registers allow the user to read the current temperature and input WW = Work Week voltages, change the configuration settings, adjust each channels G = PbFree Package limits and set set the output DAC voltages on each of the 12 channels 1 available. The NCD9812 is available in a 64lead QFN package and 64lead NCD9812 TQFP operates over a temperature range of 40 to +125C.
