DESCRIPTION
Demonstration circuit DC1969A is a kit of: the DC1967A‑A/B
LTC
®
4120EUD
demonstration board, the DC1968A basic
wireless transmitter, a 35mm receiver ferrite disk, and
an assortment of different length standoffs. The basic
transmitter can deliver 2W to the receive board with up
to 10mm spacing between the transmit and the receive
coils. The basic transmitter does not support foreign object
detection, i.e. coins or other metallic objects.
