The IQS232 is a fully integrated 2 channel self capacitance contact and proximity sensor with market leading sensitivity and automatic tuning to the sense electrode. The IQS232 provides a cost effective implementation in a small outline package. The device is ready for use in a large range of applications requiring direct outputs (2 x Touch, 1 x Proximity), while the I2C compatible interface provides full control for debugging.
