MAX1153

19-2839; Rev 1; 6/10 MAX1153/MAX1154 Stand-Alone, 10-Channel, 10-Bit System Monitors with Internal Temperature Sensor and VDD Monitor General Description The MAX1153/MAX1154 are stand-alone, 10-channel (8 external, 2 internal) 10-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 MAX1153/MAX1154 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 allow the selection of the sample rate. At the maximum sampling rate of 94ksps (auto mode, single channel enabled), the MAX1153 consumes only 5mW (1.7mA at 3V). AutoShutdownTM reduces ...
