The ALC122 is a Stereo BTL or Mono PBTL Class-D audio amplifier that can drive speakers at a typical 4Ω in BTL mode or 2Ω in PBTL mode. Its maximum output power is up to Stereo BTL 3W at 5V power supply or Mono PBTL 6W at 5V power supplied when PBTL=H.
The ALC122 provides three volume control mechanisms; 64 steps I2C Volume Control, 64 steps PWM Duty Volume Control, and 4-Steps Fixed gain Volume Control.
PWM Duty Volume Control is patented by Realtek and useful for volume control in LCD monitor systems. With Realtek proprietary Class-D amplifier technology, the ALC122 offers good audio quality, high power-efficiency, requires fewer external components, and supports analog input.
The ALC122 can output power directly to the speaker with less power dissipation inside the silicon. This high efficiency with less run-time power consumption can greatly extend the battery life of portable consumer electronic devices and notebook PCs.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
ALC122 is an authentic electronic component manufactured by Realtek, categorized under Amplifier 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 ALC122 datasheet above.
Electronic component spot-market pricing for ALC122 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 ALC122 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.

RTL8127-CG brings 10GbE to compact PCs, but the PCIe link, switch ports and cabling decide whether you see 10GbE end to end. YG GROUP sources the controller code your platform actually validated. Compare measured throughput with a 5GbE upgrade before selecting hardware, then confirm quantities and required dates.

STM32N657X0H3Q brings NPU acceleration to edge AI, but model size, external flash, RAM use and deployment tools decide whether a design fits. YG GROUP therefore quotes the MCU together with your approved memory BOM. Review those constraints before committing, then share exact order codes, quantities and target dates for a sourcing discussion.

In a BQ76952PFBR pack, the top cell can receive less average balancing current because measurements interrupt balancing, so configuration matters as much as the part. YG GROUP sources the full part number once settings are defined. Review configuration, timing and thermal limits for your LiFePO4 pack, then share cell count and quantities.

LTC4286AUK#PBF protects 48 V AI server boards during live insertion and reports power data over PMBus, but the external MOSFET's safe operating area decides survival. YG GROUP sources the controller for that validated power path. Examine inrush control, MOSFET SOA and Linux telemetry support, then specify the exact QFN variant, quantities and delivery dates.
