说明
The TSC2046 is a next-generation version to the ADS7846 4-wire touch screen controller which supports a low-voltage I/O interface from 1.5V to 5.25V. The TSC2046 is 100% pin-compatible with the existing ADS7846, and will drop into the same socket. This allows for easy upgrade of current applicati*** to the new version. The TSC2046 also has an on-chip 2.5V reference that can be used for the auxiliary input, battery monitor, and temperature measurement modes. The reference can also be powered down when not used to c***erve power. The internal reference operates down to 2.7V supply voltage, while monitoring the battery voltage from 0V to 6V.
The low power c***umption of < 0.75mW typ at 2.
