Description

The LF base station IC TMS3705ADR allows efficient development and production of RFID readers for low power hand scanners, stationary readers and vehicle immobilizers. This base station IC drives the antenna of a TI-RFid™ transponder system to send data modulated on the antenna signal, and to detect and demodulate the response from the transponder. It allows also minimizing the external component count.
