Description

General part information

AMC80 Series

The AMC80 is a system hardware monitoring and control circuit that includes a seven-channel, 10-bit analog-to-digital converter (ADC), two programmable fan-speed monitors, and a two-wire interface. The AMC80 also includes programmable upper over-limit and lower under-limit alarms that activate when the programmed limits are exceeded.

The AMC80 can interface with both linear and digital temperature sensors. The 2.5-mV least significant bit (LSB) and 2.56-V input range can accept inputs from a linear sensor such as the TMP20. TheBTIpin is used as an input from a digital sensor such as the TMP75. The AMC80 operates from a 3-V to 5.5-V supply voltage, has low supply current, and can be configured using a two-wire interface, thus making it ideal for a wide range of applications.

The AMC80 is available in a 24-lead TSSOP package and is fully specified over the –40°C to +125°C temperature range.
