Texas Instruments LMT01 2 引脚温度传感器

德州仪器 LMT01 2 引脚温度传感器是高精度温度传感器,带有易于使用的脉冲计数接口,使其成为 PTC 或 NTC 热敏电阻理想的数字化替代品。这些传感器适用于汽车、工业和消费电子市场中的板载和板外应用。LMT01 的数字脉冲计数输出和宽温度范围内的高精度特性使其能够与任何 MCU 配用,且无需担心集成模数转换器的质量或可用性,同时将软件开销降至最低程度。LMT01 在宽温度范围内具有达 ±0.5°C 的精度及极高的分辨率(0.0625°C),且无需系统校准或硬件/软件补偿。

特性

  • High accuracy over -50°C to 150°C (-40°C to 150°C for -Q1) wide temperature range:
  • -20°C to 90°C: ±0.5°C (max)
  • 90°C to 150°C: ±0.62°C (max)
  • -50°C to -20°C: ±0.7°C (max) (-40°C to -20°C: ±0.7°C for -Q1)
  • Precision digital temperature measurement simplified in a 2-pin package
  • Single-wire pulse count digital output easily read with processor timer input
  • Number of output pulses is proportional to temperature with 0.0625°C resolution
  • Communication frequency of 88kHz
  • Continuous conversion plus data-transmission period of 100ms
  • Conversion current of 34µA
  • Floating 2V to 5.5V (VP-VN) supply operation with an integrated EMI immunity
  • 2-pin package offering TO-92/LPG (3.1mm × 4mm × 1.5mm) - ½ the size of traditional TO-92
