MAX1153/MAX1154 19-2839 Rev 1 6/10 Stand-Alone, 10-Channel, 10-Bit System Monitors with Internal Temperature Sensor and V Monitor DD General Description Features Monitor 10 Signals Without Processor The MAX1153/MAX1154 are stand-alone, 10-channel (8 Intervention external, 2 internal) 10-bit system monitor ADCs with internal reference. A programmable single-ended/dif- Eight External Channels Programmable as ferential mux accepts voltage and remote-diode tem- Temperature or Voltage Monitors perature-sensor inputs. These devices independently Intelligent Circuitry for Reliable Autonomous monitor the input channels without microprocessor Measurement interaction and generate an interrupt when any variable Programmable Digital Averaging Filter exceeds user-defined limits. The MAX1153/MAX1154 Programmable Fault Counter configure both high and low limits, as well as the num- Precision Measurements ber of fault cycles allowed, before generating an inter- 10-Bit Resolution rupt. These ADCs can also perform recursive data 0.5 LSB INL, 0.5 LSB DNL averaging for noise reduction. Programmable wait inter- 0.75C Temperature Accuracy (typ) vals between conversion sequences allow the selection Flexible of the sample rate. Automatic Channel Scan Sequencer with At the maximum sampling rate of 94ksps (auto mode, Programmable Intervals single channel enabled), the MAX1153 consumes only Programmable Inputs: Single Ended/Differential, TM 5mW (1.7mA at 3V). AutoShutdown reduces supply Voltage/Temperature current to 190A at 2ksps and to less than 8A at 50sps. Programmable Wait State Stand-alone operation, combined with ease of use in a Internal 2.5V/4.096V Reference small package (16-pin TSSOP), makes the MAX1153/ (MAX1153/MAX1154) MAX1154 ideal for multichannel system-monitoring Remote Temperature Sensing Up to 10m applications. Low power consumption also makes (Differential Mode) these devices a good fit for hand-held and battery-pow- Single 3V or 5V Supply Operation ered applications.
