We’ve come a long way from cat’s whiskers and triode valves to digital tuning. The ZK8829 is a digital radio IC that can pick up AM, FM and shortwave, and can be controlled by a potentiometer or resistor string. It’s the same IC as in our Cardboard Radio Kit. Comes in 16 pin SOIC package, PI6530 SMD-DIP adaptor is recommended for prototyping.
60 - 112MHz FM band
504 - 1750kHz AM band
2.2 - 22MHz Shortwave band
1.6V - 3.6V Supply voltage.
