Low-Voltage I/O Touch Panel Controller
LN2046
■ Description
The LN2046 touch panel controller IC is a 12-bit ADC converter with SPI serial interface and low on-resistance drivers for 4-wire resistive touch panels. The LN2046 is a highly integrated controller for portable applications with 4-wire resistive touch panel such as, PDA, portable instruments, cellular phone, etc. The LN2046 consumes only 800µW at a 125kHz sample rate and a 2.7V supply and consumes only 0.3µW at shutdown mode. The LN2046 is guaranteed down to 2.7V supply. The LN2046 is provided in a very small 16-lead TSSOP and QFNWB4×4 package and is guaranteed over the temperature range.
