The RT9123GQW-2C from Richtek is a high-efficiency mono Class-D audio amplifier designed for demanding applications. It delivers 3.2W of output power into a 4-ohm load with less than 10% THD, and features an impressively low 8µV output noise.
This amplifier supports I2S, left-justified, right-justified, and TDM digital audio interfaces, with sample rates from 8kHz to 96kHz and data lengths up to 32 bits. It includes features like Dynamic Range Enhancement (DRE) to reduce output noise, spread spectrum frequency, and a fast 1ms turn-on time. The device can operate in HW Control Mode, simplifying driver requirements by not needing I2C commands for basic on/off functions.
Protection features include Over Current Protection (OCP), Under Voltage Protection (UVP) for VDD and VDD18, and Over Temperature Protection (OTP). The recommended junction temperature range is -40°C to 125°C, with an ambient temperature range of -40°C to 85°C.
Applications include smartphones, tablets, personal media players, portable TVs, gaming devices, and cameras. It is available in WL-CSP-14B and WDFN-12L packages.
