Introduction

44CPDG is a high-precision infrared thermopile temperature sensor for non-contact temperature measurement. It highly integrates an infrared-sensitive thermopile detector chip, a high-precision mixed-signal processing controller ASIC, a low-noise amplifier, a high-precision 24-bit ADC, and a high-precision body temperature algorithm into a DFN package, offering high integration, strong interference immunity, high reliability, and high accuracy — no secondary development required. The sensor covers a measurement range of -30°C to 600°C with multiple range options, a resolution of 0.2°C, an operating temperature of -40°C to 85°C, and supports rapid temperature measurement in 300 ms. Its high-precision temperature algorithm ensures measurement accuracy, with effective resistance to environmental interference, no temperature drift, and minimal measurement fluctuation.
