MAX6682MUA+T

MAX6682MUA+T is a thermistor-to-digital converter. The MAX6682 converts an external thermistor’s temperature-dependent resistance directly into digital form. The thermistor and an external fixed resistor form a voltage-divider that is driven by the MAX6682’s internal voltage reference. The MAX6682 measures the voltage across the external resistor and produces a 10-bit + sign output code dependent on that voltage. The 3-wire SPI™-compatible interface can be readily connected to a variety of microcontrollers. The MAX6682 is a read-only device, simplifying use in systems where only temperature data is required. Power-management circuitry reduces the average thermistor current, minimizing self-heating. Between conversions, supply current is reduced to 21µA (typ). The internal voltage reference is shut down between measurements.
