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/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.
At the maximum sampling rate of 94ksps (auto mode,
single channel enabled), the MAX1253 consumes only
5mW (1.7mA at 3V). AutoShutdown
TM
reduces supply
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 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.
