概述

Description

AD1954YSTZ is Analog Devices’ 24-bit, stereo digital-to-analog converter (DAC). It uses a sigma-delta architecture to convert two digital audio streams into analogue stereo outputs, suitable for high-fidelity audio up to multi‑khz/hi‑res rates. Key points:
- 24-bit, stereo DAC with high dynamic range and low distortion
- Current-output DAC requiring an I/V conversion stage and an external low-pass filter
- Programmable digital filter/de-emphasis and other controls via a serial interface (SPI/I2C‑like)
- RoHS-compliant variant in the YSTZ package (specific SMT package code)
Typical applications include high-end audio players, DAC-based audio interfaces, and professional audio gear.

Features

AD1954YSTZ features (highlights):
- 24-bit stereo DAC using multibit sigma-delta architecture
- Supports audio sampling rates up to 192 kHz
- Serial data interface formats: I2S, Left-Justified, Right-Justified
- Differential current-output DAC; external I/V conversion and reconstruction filter required
- Low distortion, wide dynamic range, and low glitch energy for high-quality audio
- Recommended separation of analog and digital power supplies for best performance
- Available in a 28-pin YSTZ package
Note: External components (I/V stage and reconstruction filter) are typically needed to complete the analog output.

Package

AD1954YSTZ comes in a 28‑pin plastic LQFP package (RoHS-compliant).

Pinout

- Pin count: 28 pins
- Function: 24-bit stereo digital-to-analog converter (DAC) with differential current-output channels; accepts serial digital audio input (I2S/Left-Justified) and requires external output conversion (op-amps) for analog signals.

Manufacturer

Analog Devices, Inc. (Analog Devices) manufactures the AD1954YSTZ. Analog Devices is an American multinational semiconductor company that designs and manufactures high-performance analog, mixed-signal, and DSP integrated circuits.

Application

AD1954YSTZ is a high‑performance stereo DAC. Common applications include:
- Hi‑fi components (digital front ends, DACs in amplifiers)
- Professional audio gear (interfaces, mixers, mastering consoles)
- Consumer A/V and disc players (Blu-ray/DVD players, streamers)
- Broadcast and post‑production equipment
- Audio test and measurement gear (reference DACs)
- Recording studios and DAW setups requiring pristine D/A conversion
