TDA 5220 ASK/FSK Single Conversion Receiver is a wireless control component.
The TDA 5220 is a very low power consumption single‑chip FSK/ASK super‑heterodyne receiver designed for frequency bands 810‑870 MHz and 400‑440 MHz. It integrates a low‑noise amplifier, double‑balanced mixer, VCO, PLL synthesiser, crystal oscillator, limiter with RSSI generator, FSK demodulator, data filter, data slicer with selectable thresholds, and a peak detector, plus a power‑down feature for battery‑powered applications.
Key features include supply currents as low as 5.0 mA (ASK) or 5.7 mA (FSK) typical, a 5 V ±10 % supply range, 50 nA power‑down current, ASK sensitivity better than –106 dBm and FSK sensitivity better than –100 dBm over –40 °C to 105 °C, and selectable frequency ranges. Typical applications are keyless entry, remote control, alarm, and low‑bitrate communication systems.

The typical supply current in FSK mode is 5.7 mA (low) to 5.9 mA (high).
It can operate in the 810‑870 MHz band and the 400‑440 MHz band.
In power‑down mode the device draws about 50 nA typical.
