TDA7535

ADCs/DACs - Special Purpose Overview

The TDA7535 is a stereo digital-to-analog converter (DAC) designed for high-fidelity audio applications. It integrates a digital interpolation filter, a third-order multi-bit Delta-Sigma DAC, and a third-order Chebyshev reconstruction filter within a single CMOS device. The component supports I2S data formats and includes an on-chip PLL for system clock generation at 64 Fs. It operates on a 3.3 V power supply with a sampling rate range of 36 kHz to 48 kHz, delivering a 0.9 VRMS single-ended output dynamic range across two channels.
