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/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 MAX1153/MAX1154

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.

At the maximum sampling rate of 94ksps (auto mode,

single channel enabled), the MAX1153 consumes only

current to 190µA at 2ksps and to less than 8µA at 50sps.

Stand-alone operation, combined with ease of use in a

small package (16-pin TSSOP), makes the MAX1153/

MAX1154 ideal for multichannel system-monitoring

applications. Low power consumption also makes

these devices a good fit for hand-held and battery-pow-

ered applications.
