Overview
The LR303X series is a low-power, high-EMC-immunity capacitive touch sensor ASIC lineup, comprising two variants: LR3031A (single-channel) and LR3032A (dual-channel). This series can withstand interference from transmitting devices such as 8-watt walkie-talkie antennas in close proximity to the touch point. Featuring proprietary core technology, high-performance anti-interference circuitry, and high-speed self-capacitance sensing, the series delivers ultra-high sensing sensitivity combined with ultra-low standby power consumption, while simplifying system design complexity and improving operational stability. Operating temperature range: -40°C ~ 85°C. Widely used in consumer electronics and industrial control applications.
Applications
