GENERAL DESCRIPTION
The AD1839A is a high performance single-chip codec that features three stereo DACs and one stereo ADC. Each DAC comprises a high performance digital interpolation filter, a multibit Σ-∆ modulator featuring Analog Devices’ patented technology, and a continuous-time voltage-out analog section. Each DAC has independent volume control and clickless mute functions. The ADC comprises two 24-bit conversion channels with multibit Σ-∆ modulators and decimation filters.
