CT8233LG / LQG / LGK is a single-channel capacitive in-ear detection chip with built-in voltage stabilization module, which is specially designed to replace in-ear sensor detection.
Working voltage: 2.4~5.5V
Working current: less than 1.5uA@3.0V No load (low power consumption mode)
Complete initialization within 0.5s after power-on is stable
Environment adaptive function, which can quickly deal with similar application scenarios such as power-on before covering media, touch power-on and so on
Reliable power-on reset (POR)
Built-in dithering circuit can effectively prevent misoperation caused by external noise interference
There is no maximum output time limit for keys
High/low level effective output, synchronization/hold mode can be set
Standard/ultra-high sensitivity, low power consumption/fast mode can be selected
CMOS push-pull output: CT8233LG/LQG
NMOS open drain output: CT8233LGK
Packaging form: SOT23-6L
