LM8300, LM8 Datasheet (National Semiconductor) - Four Wire Resistive Touchscreen Controller

LM8300 - 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
