Overview
The TDA7708CBTR is a single-chip, fully-CMOS AM/FM tuner designed by STMicroelectronics for use in automotive and other terrestrial radio broadcasting receivers. This integrated and optimized RF tuner supports AM/FM reception and is also compatible with HD-Radio™ and DRM (Digital Radio Mondiale) when paired with external co-processors like the STA680 for HD-Radio™ and the STA660DRM for DRM. The device is AEC-Q100 qualified, ensuring it meets the stringent quality and reliability standards required for automotive applications. It features a low-IF, DSP-based architecture and includes multiple front-end low-noise amplifiers (LNAs) to cover AM LW/MW/SW bands and the entire FM band, along with advanced automatic gain control (AGC) and mixer stages.
