MCP9700

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This Microchip datasheet covers the MCP9700, MCP9700A, MCP9701, and MCP9701A family of low-power linear active thermistor ICs. These devices convert temperature directly to an analog voltage without needing extra signal conditioning, making them ideal for connecting straight to microcontroller ADCs. Key specifications include a wide operating voltage range of 2.3V to 5.5V and extremely low typical current consumption of just 6µA. The sensors offer high accuracy within ±2°C between 0°C and 70°C for the 'A' versions, while supporting extended ranges up to +150°C. Available in TO-92, SOT-23, and SC70 packages, these chips are optimized for applications like hard drives, home appliances, and battery monitoring systems.
