Overview

Description

AD1835AASZ is an Analog Devices stereo audio converter (part of the AD1835 family). It is a high‑fidelity, 24‑bit sigma–delta device designed for audio applications.
Key points
- Functions: differential analog inputs/outputs with a digital audio interface (I2S/left-justified or similar) for stereo audio.
- Architecture: sigma‑delta core suitable for low distortion and high dynamic range.
- Packaging: the AASZ suffix denotes a specific RoHS‑compliant package variant used by Analog Devices (exact pinout/package size specified in the datasheet).
Typical uses
- Professional and consumer audio equipment, audio interfaces, DAC/ADC stages in mixers, sound cards, and digital audio processing chains.
Note
- For exact specifications (sampling rates, SNR, THD, power, pinout), refer to the AD1835AASZ datasheet. The suffix mainly indicates the package/leadframe variant.

Features

AD1835AASZ features (highlights):
- Stereo 24-bit delta-sigma analog-to-digital converter
- Internal digital decimation filter with flexible output formats
- Supports standard audio sample rates up to 96 kHz (e.g., 44.1/48/88.2/96 kHz)
- Differential analog inputs with integrated anti-alias filter
- Flexible digital interface: I2S, left-justified, right-justified, DSP formats
- Two’s-complement digital output; clocking supports master/slave operation
- Low power consumption with power-down modes
- Wide operating temperature range (-40°C to +85°C)
- Suitable for consumer/industrial audio applications in the AASZ package
Note: exact specifications (gain, input range, power, packaging) are in the datasheet for the AASZ variant.

Package

The AD1835AASZ comes in a RoHS-compliant LQFP (lead-free) package with 28 pins.

Pinout

- Pin count: 28 pins (package varies, commonly 28-pin LQFP/SOIC).
- Function: Stereo analog-to-digital converter (audio A/D) with differential inputs and a serial digital output/interface (audio data interface such as I2S/left-justified).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and DSP (digital signal processing) integrated circuits and system solutions for various industries.

Application

- High-resolution stereo audio front-end (ADC) for consumer and professional audio
- Digital recorders, mixers, and audio interfaces
- Sound cards and DSP-based audio processing in broadcast/telecom
- Instrumentation and measurement systems for acoustics, audio analysis, and related tests

Equivalent

AD1835AASZ is a 24‑bit stereo sigma‑delta ADC up to 96 kHz with an I2S/Left-Justified interface. Potential equivalents from other vendors: Cirrus Logic CS5340 (24-bit stereo ADC, 96 kHz, I2S); Cirrus Logic CS5344 (24-bit stereo ADC, 96 kHz, I2S); TI PCM1802 (24-bit stereo ADC, 96 kHz); TI PCM1804 (24-bit stereo ADC, 96 kHz). Note: verify pinouts and interfaces, as cross‑compatibility isn’t guaranteed.
