Product Brief
TDA 7210V
ASK/FSK Receiver for the 434 and 868MHz
frequency bands in a tiny VQFN package
More and more consumer products become small and smaller and
engineers try hard to reduce PCB area and cost wherever possible.
With TDA 7210V Infineon offers a VQFN-32 package variant of its popular
TDA 7210 receiver for very size sensitive applications like small set-top-box
designs or lighting control receiver which have to fit into a light bulb.
TDA 7210V is an ASK/FSK superheterodyne receiver for the 434 and 868MHz
ISM-bands targeting all industrial and consumer applications. The device
is highly integrated and requires only a few external components. The low
current consumption of only 5mA and a typical ASK sensitivity of -115 dBm at a
datarate of 1kbit/s are the key benefits of this IC.
