Overview
The MAX1253BEUE+T, produced by Analog Devices Inc./Maxim Integrated, is a stand-alone, 10-channel (8 external, 2 internal) 12-bit system monitor analog-to-digital converter (ADC). This device features an internal reference and a programmable single-ended/differential multiplexer that accepts voltage and remote-diode temperature-sensor inputs. It is designed for independent monitoring of input channels without the need for microprocessor interaction and can generate interrupts when user-defined limits are exceeded. The MAX1253BEUE+T is known for its low power consumption and compact 16-pin TSSOP package, making it ideal for multichannel system-monitoring applications, including hand-held and battery-powered devices.
