Descripción general

Description

AD1955ARSZRL is Analog Devices’ 24-bit stereo digital-to-analog converter (DAC). It uses a current-output architecture intended for high-fidelity audio and supports PCM input up to 192 kHz/24-bit. The DAC requires an external I/V conversion stage and an analog reconstruction filter. It offers selectable digital filter options and aims for low distortion with a wide dynamic range, suitable for high-end audio and professional gear. The ARSZRL suffix indicates the specific RoHS-compliant packaging/version of the device. For exact electrical specs, pinout, and recommended external components, consult the AD1955 datasheet and package data sheet.

Features

AD1955ARSZRL features:
- 24‑bit stereo DAC with multibit sigma–delta architecture
- Supports PCM up to 192 kHz sample rate
- Differential current-output DAC; requires external I/V conversion and buffer
- Digital input interfaces: I2S, Left-Justified, Right-Justified (PCM data formats)
- Internal digital filtering with selectable responses; optional digital de-emphasis
- Soft mute and pop/noise suppression at power-up/down
- Power-down/wake functionality and low-power modes
- Clocking: tolerant to clock jitter with flexible clock options
- Compact ARSZRL packaging (integration-friendly for high-end audio boards)
Note: External analog I/V and buffer stages are typically used to convert current outputs to voltage.

Package

AD1955ARSZRL is in a 28‑pin LQFP (lead-frame quad flat package), RoHS-compliant lead-free variant.

Pinout

- Pin count: 28 pins
- Function: 24-bit stereo digital-to-analog converter (DAC) for audio (up to 192 kHz); provides differential current outputs and requires an external I/V stage and reconstruction filter. Digital input typically via I2S/left-justified interfaces.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (including audio DACs/ADCs, op-amps, sensors, MEMS, etc.).

Application

Application areas of AD1955ARSZRL:
- High-fidelity stereo DACs for consumer and professional audio
- DAC modules, sound cards, audio interfaces, standalone DACs
- AV equipment: receivers, SACD/CD/Blu-ray players, digital music players
- Studio gear: digital mixers, mastering consoles, monitoring systems
- High-end headphone amplifiers and preamps

Equivalent

AD1955ARSZRL is a 24‑bit, stereo DAC from Analog Devices. There isn’t a direct drop‑in equivalent from ADI. Closest non‑ADI substitutes with similar performance include Cirrus Logic CS4398/CS4397, TI PCM5102A (or PCM5242), AKM AK4452/AK4490, and ESS ES9023/ES9028. Note that pinout, I/V stage, and external components differ; verify each datasheet for interface (I2S), master/slave, supply rails, and filtering. For exact compatibility, consider another DAC in the same ADI family or request ADI’s recommended replacement.
