LM8300, LM8, Four Wire Resistive Touchscreen Controller
The LM8300/8400/8500 is a 4-wire resistive touch screen controller.
The controller samples and drives the touch screen without the need of any external hardware.
The built in 10-bit A/D provides a maximum of 500 coordinate pairs per second (cpps).
The data sampled from the touch screen is sent out o
