Description
This evaluation kit consists of 2 x LTC4123 button cell size evaluationboards, and a custom LTC4125 transmitter evaluationboard. The transmitter board is customized to deliver 1mA ofcurrent into the button cell sized LTC4123 boards placed in thedish with maximum freedom of placement. The button cellsboard features the LTC4123 which is available in a 2mm x 2mmDFN package. The custom transmitter does not support conductiveforeign object detection, for example coins or other metallicobjects
