MCP9800 - 2-Wire High-Accuracy Temperature Sensor

General Description

Microchip Technology Inc.’s MCP9800/1/2/3 family of digital temperature sensors converts temperatures between -55°C and +125°C to a digital word.

They provide an accuracy of ±1°C (maximum) from -10°C to +85°C.

Key Features

  • Temperature-to-Digital Converter.
  • Accuracy with 12-bit Resolution: - ±0.5°C (typical) at +25°C - ±1°C (maximum) from -10°C to +85°C - ±2°C (maximum) from -10°C to +125°C - ±3°C (maximum) from -55°C to +125°C.
  • User-selectable Resolution: 9-12 bit.
  • Operating Voltage Range: 2.7V to 5.5V.
  • 2-wire Interface: I2C™/SMBus Compatible.
  • Operating Current: 200 µA (typical).
  • Shutdown Current: 1 µA (maximum).
  • Power-saving One-shot Temper.
