MAXIM MAX1253/MAX1254 Manual

Update: 30 September, 2023

The MAX1253/MAX1254 are 10-channel (8 external, 2 internal) 12-bit system monitor ADCs with internal reference. A programmable single-ended/diff- 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). AutoShutdownTM 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.
