MICRF009BM

RF Receiver ASK/OOK 5V 16Pin SOIC N

General Description  

The MICRF009 is a single chip, ASK/OOK ON-OFF Keyed RF receiverIC. It provides thesamefunction but with performance enhancements over earlier QwikRadio® receivers. Two key improvements are: higher sensitivity

typically 6dBhigher than the MICRF002  andfaster recoveryfromshutdown typically 1ms. Just like all other

members ofthe QwikRadio® family, the MICRF009 achieves low power operation, a very high level of integration, and it is particularly easy to use.
