產品總覽

The MAX6682MUA+ is a thermistor to digital converter in 8 pin µMAX package. It converts an external thermistor temperature dependent resistance directly into digital form. The thermistor and an external fixed resistor form voltage divider that is driven by internal voltage reference of MAX6682. The device measures voltage across the external resistor and produces 10bit resolution and sign output code dependent on that voltage. The MAX6682 does not linearize highly nonlinear transfer function of typical negative temperature coefficient thermistor but it does provide linear output data over limited temperature ranges when used with an external resistor of correct value. It produces output data that is scaled to 8LSBs/°C (for 0.125°C resolution) over 0° to 50°C temperature range provided that correct thermistor and external resistor values are used. Other temperature ranges can be easily accommodated but do not necessarily yield data scaled to an even number of LSBs per degree.
  • Supply voltage range from 3V to 5.5V
  • Operating temperature range from -55°C to 125°C
  • Low average thermistor current minimizes self heating errors
  • Low supply current of 21µA including 10Kohm thermistor current
  • Internal voltage reference isolates thermistor from power supply noise
  • Read-only device, simplifies use in systems where only temperature data is required
  • Average supply current of 17µA an standby current of 3µA
  • 5MHz, 3-wire SPI compatible interface
  • Conversion rate of 0.5Hz and conversion supply current of 220µA
  • ADC total unadjusted error of ±3LSB and ADC conversion time of 64ms
