AB1562 Product Brief BENEFITS applications filter drivers  Low power consumption for BT audio PRODUCT OVERVIEW  BT RF with on-chip balun and band pass The AB1562 series, intended for Bluetooth audio applications, integrates the PMU, DSP, BT, and audio functions into a single chip. The Tensilica HiFi Mini DSP is a general processor and used for audio data processing. The Bluetooth RF, integrating the balun and the band pass filter, provides good TX/RX performance. High performance audio drivers and hardware active noise cancellation circuits are also included for better audio quality. In addition, the power management IC (PMIC) with fast charging is SiP(system-in-package) in the package to shorten the battery charging time. The flash memory are also SiP for easier PCB design.
