The AD71028 dual digital BTSC encoder provides two complete digital BTSC encoder channels, including the pilot-tone generation and subcarrier mixing functions. Two built-in high performance DACs are provided to output the BTSC baseband composite signal. The output of the AD71028 can be connected with minimal external circuitry to the input of a 4.5 MHz aural FM modulator.In addition to the BTSC encoders, the AD71028 also includes a stereo image enhancement function, Phat Stereo, to increase the sense of spaciousness available from closely spaced TV loudspeakers. A dialog enhancement algorithm is also included to solve the problem of playing wide dynamic range sources over limited-performance TV speakers and amplifiers. An extensive SPI port allows click-free parameter updates. The AD71028 also includes ADI’s patented multibit Σ-Δ DAC architecture. This architecture provides 92 dB SNR and THD+N of -92 dB.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
AD71028 is an authentic electronic component manufactured by Analog Devices, categorized under Multimedia ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official AD71028 datasheet above.
Electronic component spot-market pricing for AD71028 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for AD71028 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
