General Description

The MICRF002 is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. This device is a true “antenna-in to data-out” monolithic device. All RF and IF tuning is accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution. The MICRF002 is a fully featured part in 16-pin packaging, the MICRF022 is the same part packaged in 8-pin packaging with a reduced feature set (see “Ordering Information” for more information).
