Technical Specifications:

The TDA5231XUMA1 operates from a supply voltage of 2.1V to 3.6V. It features low current consumption in both active and standby modes. It is capable of ASK and FSK demodulation, providing flexibility in modulation schemes. The RSSI output provides an indication of the received signal strength. The wake-up timer enables the device to conserve power by periodically checking for a valid signal. The AGC ensures optimal receiver performance over a wide range of input signal levels. The data slicer converts the received signal into a digital data stream.

The TDA5231XUMA1 is available in a small SMD package, making it suitable for space-constrained applications. Its low power consumption and high sensitivity make it an excellent choice for battery-powered wireless devices. It is often found in applications that require wireless communication over short to medium distances.
