PRODUCT DESCRIPTION

The AD6652 is a mixed-signal IF to baseband receiver consisting of dual 12-bit 65 MSPS ADCs and a wideband multimode digital downconverter (DDC). The AD6652 is designed to support communications applications where low cost, small size, and versatility are desired. The AD6652 is also suitable for other applications in imaging, medical ultrasound, instrumentation, and test equipment.
