with Internal Temperature Sensor and V Monitor

General Description  
Features  
o Monitor 10 Signals Without Processor  
The MAX1253/MAX1254 are stand-alone, 10-channel (8  
external, 2 internal) 12-bit system monitor ADCs with  
internal reference. A programmable single-ended/dif-  
ferential mux accepts voltage and remote-diode tem-  
perature-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 num-  
ber of fault cycles allowed, before generating an inter-  
rupt. These ADCs can also perform recursive data  
averaging for noise reduction. Programmable wait inter-  
vals between conversion sequences allow the selection  
of the sample rate.  
Intervention  
o Eight External Channels Programmable as  
Temperature or Voltage Monitors  
o Intelligent Circuitry for Reliable Autonomous  
Measurement  
Programmable Digital Averaging Filter  
Programmable Fault Counter  
o Precision Measurements

Programmable Inputs: Single Ended/DifferentialL  
Voltage/Temperature  
At the maximum sampling rate of 94ksps (auto mode,  
single channel enabled), the MAX1253 consumes only  
5mW (1.7mA at 3V). AutoShutdownTM reduces supply  
current to 190µA at 2ksps and to less than 8µA at 50sps.  
Programmable Wait State  
o Internal 2ꢂ7V/4ꢂ096V Reference  
ꢃMAX1273/MAX1274ꢄ  
Stand-alone operation, combined with ease of use in a  
small package (16-pin TSSOP), makes the MAX1253/  
MAX1254 ideal for multichannel system-monitoring  
applications. Low power consumption also makes  
these devices a good fit for hand-held and battery-pow-  
ered applications.
