Product Summary

The TDA5235 is an ASK/FSK Autonomous Receiver. The applications of the TDA5235 include Remote keyless entry systems, Remote start applications, Tire pressure monitoring, Remote control units, Cordless alarm systems, Remote metering.

Parametrics

TDA5235 absolute maximum ratings: (1)Receiving current: 15mA; (2)Operating temperature: -40 to 105℃; (3)Supply voltage: 3V to 3.6V; 4.5V to 5.5V; (4)Sensitivity: -117dBm.

Features

TDA5235 features: (1)Highest sensitivity receiver Typ. -118 dBm for FSK; Typ. -116 dBm for ASK; (2)Autonomous receive mode leads to reduced noise of host processor, improved sensitivity and reduced power consumption of the system; (3)Up to 4 (TDA5240)/ 2 (TDA5235) parallel parameter sets and up to 12 different frequency channels(TDA5240 only); (4)Several embedded encodings and modulation schemes; (5)Ultrafast Fallback Wake-up criterion reduces receiver’s active time, when no data available.
