Description:

2 KEY QTOUCH SENSOR IC

Features

* spread-spectrum acquisition capability, external synchronization of acquire bursts, and fast and slow acquisition modes. These modes are enabled via high-value resistors connected to the SNS pins to ground or Vdd. These resistors are required in every circuit. There are two basic modes as shown in F
