        CT8233LGK is a single channel capacitive in ear detection chip with built-in voltage regulator module, designed specifically to replace in ear sensor detection. Made using CMOS technology, it integrates various effective measures such as high-precision voltage stabilization, hardware jitter reduction, and environmental value adaptive algorithms, greatly improving its anti-interference performance. It can achieve touch function and high safety with isolation protection of media (such as plastic casing, glass ceramic, acrylic, etc.). With ultra-low power consumption and wide working voltage characteristics, stable in ear detection effect, widely used in consumer wear detection products such as in ear Bluetooth earphones, achieving product intelligence.
