MAX1153 Datasheet PDF - Maxim Integrated

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). AutoShutdown™ 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 MAX1153/MAX1154 ideal for multichannel system-monitoring applications. Low power consumption also makes these devices a good fit for hand-held and battery-powered applications.
