Description
AD1955ARSZRL is Analog Devices’ AD1955 24‑bit stereo digital‑to‑analog converter (DAC). It converts digital audio data into an analog stereo output suitable for high‑fidelity audio gear. Typical features (as with the AD1955 family) include 24‑bit resolution, support for common digital interfaces (I2S, left‑justified, DSP formats), and options for digital filtering; it is designed to be used with an external I/V stage and reconstruction filter. The ARSZRL suffix denotes the specific manufacturing/packaging: SZ package, RoHS/compliant lead‑free variant, shipped in tape‑and‑reel form. For exact electrical specs, pinout, and packing details, refer to the AD1955 datasheet and packaging guide.
Equivalent
AD1955ARSZRL is a 24-bit, stereo, 192 kHz Delta-Sigma DAC. Close-performing equivalents include Cirrus Logic CS4398, TI PCM1794A/PCM1795, and Wolfson WM8740/WM8741. Exact pinout/package differ; check ADI’s cross-reference tool or distributor data for precise swap.
Features
AD1955ARSZRL features:
- 24-bit stereo DAC with high-performance sigma-delta architecture
- PCM sample rates up to 192 kHz
- Differential current-output DAC; requires external I/V stage
- Internal digital filter with selectable options
- Supports standard digital audio interfaces (I2S, left-justified, right-justified)
- Flexible clocking: external master clock input with low jitter; optional PLL
- Soft-mute/pop-noise suppression on power-up/down
- High dynamic range and low distortion (typical SNR and THD+N suitable for high-end audio)
- Low power operation and wide temperature range
- RoHS-compliant 28-pin package (ARSZRL) suitable for compact designs
Note: For exact electrical specs (SNR, THD+N, currents, power pins), refer to the AD1955 data sheet.
