The AD1882A audio codec and software provide superior HD audio quality and performance. The AD1882A has six DACs and four ADCs, two stereo headphone ports,C/LFE swapping, digital and analog PCBeep, and S/PDIF output, making the AD1882A the right choice for desktop PCs where performance is the primary consideration.
The Conexant AD1882A is a high-definition audio codec designed for desktop PCs and embedded applications. It integrates six Digital-to-Analog Converters (DACs) and four Analog-to-Digital Converters (ADCs), along with two stereo headphone ports, C/LFE swapping capabilities, and S/PDIF output.
The device supports advanced features such as digital synthesis PCBeep, a digital microphone with programmable clock output, and jack re-tasking for various platform configurations. It is available in a 48-lead RoHS compliant lead frame chip scale package (QFN) and operates within temperature ranges of 0°C to 70°C or -20°C to 85°C depending on the specific ordering ID.
