Microchip MCP9700-E/TO Linear Active Thermistor IC for Analog Temperature Sensing

In the realm of temperature measurement, the Microchip MCP9700-E/TO stands out as a highly reliable and cost-effective solution for analog temperature sensing. This linear active thermistor IC is engineered to provide an accurate and straightforward method for converting temperature into an analog voltage, making it an ideal choice for a wide range of applications, from consumer electronics to industrial systems.

The MCP9700-E/TO operates over a wide temperature range of -40°C to +125°C, ensuring robust performance in diverse environments. Unlike traditional thermistors, which exhibit a non-linear resistance-temperature relationship, this device delivers a linear output voltage that is directly proportional to the measured temperature. This linearity significantly simplifies the signal conditioning process, reducing the need for complex calibration or lookup tables. The output slope is typically 10 mV/°C, with a DC offset of 500 mV at 0°C, allowing for easy interfacing with microcontrollers or analog-to-digital converters (ADCs).

Housed in a TO-92 package, the MCP9700-E/TO is designed for through-hole mounting, offering mechanical durability and ease of prototyping. Its low operating current of 6 μA (typical) makes it exceptionally suitable for battery-powered and low-energy applications, minimizing power consumption without compromising performance. Additionally, the device features a fast response time and excellent accuracy, with ±2°C precision from 0°C to +70°C.

Key applications include environmental monitoring, HVAC systems, portable medical devices, and automotive subsystems, where precise temperature data is critical. The MCP9700-E/TO provides a seamless and efficient path from thermal sensing to analog voltage output, enhancing system reliability and design flexibility.
