The SX8650 4-wire resistive touchscreen controller with enhanced ±15kV ESD protection, consumes 23 µA at 8 ksamples/s. The part supports the 400-kHz fast-mode I2 C serial bus data protocol and has an operating voltage from 1.65 to 3.7 V. In addition, it features a highly accurate 12-bit ADC for coordinates and touch pressure measurement, and can achieve an equivalent throughput output rate of 50 ksamples/s.
Housed in both 12-DFN and 12-WLCSP packages, the SX8650 also features a dedicated hardware/reset pin, a built-in preprocessing algorithm for data averaging, and an operating temperature from –40° to 85°C. (Ea/3,000: DFN package, $0.76; WLCSP package, $0.78 — prod qty available now.)
