Overview
The TDA7708, produced by STMicroelectronics, is a single-chip, fully-CMOS AM/FM tuner designed for receivers in terrestrial radio broadcasting. This integrated and optimized RF tuner is tailored for AM/FM reception and can also support HD-Radio™ and DRM solutions when paired with external co-processors like the STA680 for HD-Radio™ and the STA660DRM for DRM. The TDA7708 is particularly suited for automotive grade receivers and other applications requiring high performance, reliability, and cost efficiency.
