TDA 7255V Reduces Costs and Footprint

Infineon TDA 7255V

As consumer devices continue to shrink, engineers are working hard to reduce PCB area and costs wherever possible.

TDA 7255V is a VQFN-40 package variant of Infineon’s popular TDA 5255 transceiver. This new device comes in a tiny package and delivers highest sensitivity performance. It is targeted specifically at highly size-sensitive industrial and consumer applications, such as small home automation or security and alarm systems.

Infineon - TDA 7255V

TDA 7255V is an ASK/FSK single-channel transceiver for the 434MHz ISM frequency band. The device is highly integrated and requires only a few external components. The extreme low current consumption in receive, transmit and power-down mode and the wide supply voltage range make it ideal for home automation, industrial controls and low-bit-rate communications.
