ADC Timing Diagrams
Figure 82 represents the synchronization between the signals clk, soc, eoc, and the output bits in the usage
of the internal ADC. After a conversion cycle eoc is asserted, a new conversion begins only when the

1 This comprises only the required initial dummy conversion cycle. Additional power-up time depends on the enadc, reset and
soc signals applied to the touchscreen controller.
2 This value only includes the ADC and the driver switches, but it does not take into account the current consumption in the
touchscreen plate. For example, if the plate resistance is 100 W, the total current consumption is about 33 mA.
3 At avdd = 3.3 V, dvdd = 1.2 V, Tjunction = 50 °C, fclk = 1.75 MHz, any process corner, unless otherwise noted.
4 Value measured with a –0.5 dBFS sinusoidal input signal and computed with the code density test.
