Microchip Technology MCP9600熱電対EMF対温度コンバータ

Microchip Technology MCP9600熱電対EMF-温度コンバータは、統合冷接点補償で熱電対EMFを摂氏温度に変換します。8つの熱電対タイプの熱電対非線形エラー特性を訂正し、選択された熱電対に対して±1.5°C精度の温度データを出力します。補正係数は、米国国立標準技術研究所（NIST）のITS-90熱電対データベースから取得された値です。

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.
