Features and Applications

The MICRF219AAYQS is a part of MICRF219A series having 3 V, 4.3 mA supply current ASK/OOK Receiver with Auto-Poll RSSI, and Squelch Receiver ICs.

The MICRF219A is a superheterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, analog RSSI output, and integrated squelch features. It only requires a crystal and a minimum number of external components to implement. The MICRF219A is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.
