TDA5235XUMA1

射频远程无钥门禁系统, 902MHz至928MHz, ASK, FSK, -117dBm, 3V至3.6V电源, TSSOP-28

Description:

It sounds like a contradictory combination, yet this is what is more and more requested from your receiver design: long range, low energy consumption and flexible adaptation to customer requirements. You think this requires high development effort and expensive additional components in your design? Not with our new high sensitivity, low-power receiver family SmartLEWIS RX+. The SmartLEWIS RX+ family consisting of TDA5240, TDA5235 and TDA5225 covers all those requirements with a minimum of external components.
