Description
AD1940YSTZ is Analog Devices’ 24‑bit stereo digital‑to‑analog converter (DAC) built on a high‑performance sigma‑delta core for professional audio. It converts digital audio data into high‑fidelity analog outputs suitable for high-end DACs, audio interfaces, and studio gear.
The “YSTZ” suffix denotes the packaging variant (the physical package/footprint) for ordering. For exact pinout, electrical specs, recommended operating conditions, and application notes, consult the AD1940 datasheet and packaging documentation.

Equivalent
Direct pin-for-pin equivalents for AD1940YSTZ do not exist. It’s a legacy ADI 24-bit stereo DAC with I2S. For replacements, consider functionally similar 24-bit stereo DACs with I2S, such as: TI PCM5102A/PCM5242; Cirrus Logic CS4398/CS4344; Burr-Brown PCM1704. To find a direct substitute, use Analog Devices’ cross-reference/tool with your required pinout and interface.
Features
AD1940YSTZ features (concise):
- 24-bit stereo digital-to-analog converter
- Current-output DAC with external I/V conversion and differential analog outputs
- Flexible digital interface: I2S, Left-Justified, Right-Justified
- Wide sampling-rate support up to 192 kHz
- High dynamic range with low distortion
- Low jitter tolerance and configurable digital filter/de-emphasis
- Suitable for single-supply operation in compact YSTZ package
Note: For exact electrical specifications (supply voltage, SNR/THD, pinout, and recommended external components), consult the official datasheet.
