In addition, the three Maxim ICs are low-power devices, allowing this reference design to consume minimal power with low thermal dissipation. The 3.3V and 5V rails are generated by utilizing the two integrated LDO regulators within the MAX14828, which saves external components and space. All three Maxim products are in wafer-level packages (WLPs), allowing the MAXREFDES164# to have a tiny footprint-under an inch in length. The temperature sensor performs more accurate temperature conversions from 0☌ to +70☌ (☑.0☌).Ī MAX32660 microcontroller interfaces between the MAX31875 temperature sensor and the MAX14828 IO-Link ® device transceiver. The MAX31875 operates over the -50☌ to +150☌ temperature range and measures temperatures from -40☌ to +145☌ with ☑.5☌ accuracy. Built in an industrial form factor, the design makes use of Maxim’s highly integrated MAX31875 digital temperature sensor with an I 2C interface. The MAXREFDES164# is a complete, high-accuracy, IO-Link ®, local temperature sensor reference design that provides excellent temperature accuracy from -20☌ to +105☌.
