Samsung S3C2410A User Manual

The 10-bit CMOS analog to digital converter (ADC) of the S3C2410A is a recycling typed device with 8-channel
analog inputs. It converts the analog input signal into 10-bit binary digital codes at a maximum conversion rate of
500KSPS with 2.5 MHz A/D converter clock. The A/D converter operates with on-chip, sample-and-hold function and
power down mode is supported.

The S3C2410A supports Touch Screen Interface, which consists of a touch screen panel, four external transistors,
an external voltage source, AIN[7] and AIN[5] (see Figure 16-2).
Touch Screen Interface controls and selects control signals (nYPON, YMON, nXPON and XMON) and analog pads
(AIN[7], AIN[5]) which are connected with pads of touch screen panel and the external transistor for X-position
conversion and Y-position conversion.
Touch Screen Interface contains an external transistor control logic and an ADC interface logic with an interrupt
generation logic.
