LM71-Q1 具有 SPI 接口的汽車級 ±1.5°C 溫度傳感器

數據： LM71/LM71Q SPI/MICROWIRE 13-Bit Plus Sign Temperature Sensor 數據表

描述

The LM71 is a low-power, high-resolution digital temperature sensor with an SPI and MICROWIRE compatible interface, available in the 5-pin SOT-23 or the 6-pin WSON (no pull back) package. The host can query the LM71 at any time to read temperature. Its low operating current is useful in systems where low power consumption is critical.

The LM71 has 13-bit plus sign temperature resolution (0.03125°C per LSB) while operating over a temperature range of −40°C to +150°C.

The LM71’s 2.65V to 5.5V supply voltage range, fast conversion rate, low supply current, and simple SPI interface make it ideal for a wide range of applications. The LM71Q is available in the 5-lead SOT-23 package only.
