General Description

The SX9500 is a low-cost, very low power 4-channel capacitive controller that can operate either as a proximity or button sensor.

The SX9500 includes sophisticated on-chip auto-calibration circuitry to regularly perform sensitivity adjustments, maintaining peak performance over a wide variation of temperature, humidity and noise environments, providing simplified product development and enhanced performance.

The SX9500 operates directly from an input supply voltage of 2.7 to 5.5V, and includes a separate I2C serial bus supply input to enable communication with 1.8 – 5.5V hosts.
