The MAX6682 is a temperature sensor from MAXIM, which can convert temperature into digital signals using a 3-wire SPI™ interface
The MAX6682 is a thermistor‑to‑digital converter that measures the voltage across an external resistor and provides a 10‑bit signed output code. It operates from a 3 V to 5.5 V supply, draws only 21 µA standby current, and uses a 3‑wire SPI‑compatible interface for easy connection to microcontrollers.
The device is supplied in an 8‑pin µMAX package and is specified for temperatures from –55 °C to +125 °C. Typical specifications include a 5 MHz serial clock limit, 64‑80 ms conversion time, 1 MΩ input impedance, and an average supply current of 17‑29 µA during conversion.
