SX9500IULTRT [Semtech]

SX9500IULTRT Description

The SX9500IULTRT 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. The

I²C serial communication bus reports proximity or touch detection and is used to facilitate parameter settings adjustment.
