19-2838; Rev 0; 4/03 Stand-Alone, 10-Channel, 12-Bit System Monitors with Internal Temperature Sensor and VDD Monitor General Description The MAX1253/MAX1254 are stand-alone, 10-channel (8 external, 2 internal) 12-bit system monitor ADCs with internal reference. A programmable single-ended/differential mux accepts voltage and remote-diode temperature-sensor inputs. These devices independently monitor the input channels without microprocessor interaction and generate an interrupt when any variable exceeds user-defined limits. The MAX1253/MAX1254 configure both high and low limits, as well as the number of fault cycles allowed, before generating an interrupt. These ADCs can also perform recursive data averaging for noise reduction. Programmable wait intervals between conversion sequences al [ ... ]
