The RM1101A is a high-precision ear-in+piezoelectric sensing detection chip, designed for IoT hardware devices such as smart wearables. It offers ultra-high sensitivity and ultra-low power consumption, capable of detecting the distance between a metal plate and an object. The chip quantifies this distance using a high-performance ADC and employs internal proximity detection algorithms to determine the object's distance. Upon reaching a predefined threshold, the RM1101A outputs a direct synchronous level or an event-encoded pulse waveform. Its self-calibration circuit eliminates fixed distance errors from the sensor, and configurable registers allow for adjustments and calibration based on different sensor structures and operating environments, enabling high performance and low power consumption tailored to user needs.
