Microchip Technology MCP9600 热电偶 EMF-温度转换器

微芯科技 MCP9600 热电偶 EMF-温度转换器可通过集成冷端补偿功能将热电偶 EMF 转换为摄氏温度。它校正了八种类型热电偶的非线性误差特性,并输出精度为 ±1.5°C 的所选热电偶温度数据。校正系数源自国家标准技术局(NIST)ITS-90 热电偶数据库。

The MCP960x, MCP96L0x, and MCP96RL0x feature user-programmable registers, providing design flexibility for various temperature-sensing applications. The registers allow user-selectable settings such as low-power modes for battery-powered applications and an adjustable digital filter for fast transient temperatures. These devices also allow four individually programmable temperature alert outputs, which can be used to detect multiple temperature zones.

The temperature alert limits have multiple user-programmable configurations, including alert polarity as either an active-low or active-high push-pull output, and output function as comparator mode (useful for thermostat-type operation) or interrupt mode for microprocessor-based systems. Additionally, the alerts can detect either a rising or a falling temperature with up to 255°C hysteresis.

The Microchip Technology MCP960x, MCP96L0x, and MCP96RL0x are offered in a pin-compatible 20-lead MQFN package, allowing for scalability between ICs. These modules are ideal for space-constrained applications.
