Overview
The AD1934WBSTZ, produced by Analog Devices Inc., is a high-performance, single-chip digital-to-analog converter (DAC) that features eight channels with single-ended output. This device utilizes Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture, ensuring high-quality audio conversion. The AD1934WBSTZ includes an on-chip phase-locked loop (PLL) and supports sample rates from 8 kHz to 192 kHz. It operates on a single 3.3 V supply and is designed for low electromagnetic interference (EMI). The device is available in a 48-lead LQFP package and is suitable for various audio applications requiring high fidelity and reliability.
