Overview
The AD1836AASRL is a multichannel audio codec manufactured by Analog Devices Inc. It features three stereo DACs and two stereo ADCs utilizing a multibit sigma-delta architecture. The device supports 24-bit resolution at sample rates up to 96 kHz. It operates from a 5 V supply (AVDD/DVDD range: 4.75 V to 5.25 V) with an ODVDD supply of 3.0 V to 5.25 V. Typical analog current consumption is 108 mA, while digital current is 78 mA. The ADC provides a dynamic range of 105 dB (A-weighted), and the DAC achieves 108 dB. The component is housed in a 52-lead MQFP package.
Feature Summary
- Multichannel architecture providing three stereo DACs and two stereo ADCs
- Flexible serial data port supporting I2S, DSP, left-justified, and right-justified modes
- On-chip volume control with auto-ramp function and programmable gain amplifier
- Hardware and software controllable clickless mute capability
Applications
- Home theater systems
- Automotive audio systems
- DVD recorders
- Set-top boxes
- Digital audio effects processors
Procurement Notes
Verify the specific suffix RL against official documentation to confirm reel packaging details. Confirm RoHS compliance status for the exact part number variant. Check lead times and availability as distribution channels vary. Ensure ESD precautions are observed during handling due to device sensitivity.
Selection Notes
Select this component for applications requiring multiple independent audio channels within a single integrated circuit. Verify that the system master clock can be maintained at a constant frequency when switching between 48 kHz and 96 kHz sample rates. Ensure the host processor supports the required SPI control interface and serial data formats.
Part Context
The AD1836AASRL belongs to the AD1836A family of high-performance audio codecs. This series is designed for professional and consumer audio equipment requiring low distortion and high dynamic range. The device integrates digital filters and volume controls to simplify system design.
Replacement Considerations
The AD1836AAS is a direct pin-compatible alternative without the reel suffix. Verify functional equivalence regarding electrical specifications and package dimensions before substitution.
