MAX6682 Datasheet Thermistor-to-digital Converter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. 19-2219; Rev 0; 2/02 Thermistor-to-Digital Converter General.

General Description

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.

Key Features

  • o Converts Thermistor Temperature to Digital Data o Low Average Thermistor Current Minimizes SelfHeating Errors o Low Supply Current, 21µA (typ) Including 10kΩ Thermistor Current o Internal Voltage Reference Isolates Thermistor from Power-Supply Noise o 10-Bit Resolution o Accommodates Any Thermistor Temperature Range o Output Data Scaled for Direct Temperature Readings from 0°C to +50°C o Simple SPI-Compatible Interface o Small, 8-Pin µMAX Package MAX6682 Ordering Information PART MAX6682MUA.
