AD1836ACSZ

Overview

The AD1836ACSZ is a multichannel audio codec manufactured by Analog Devices Inc., housed in a 52-lead MQFP package. It integrates two stereo ADCs and three stereo DACs, supporting resolutions up to 24 bits and sample rates up to 96 kHz. The device operates on a single 5 V supply (4.75 V to 5.25 V) with an analog current consumption of 108 mA and digital current of 78 mA. Key performance metrics include an ADC dynamic range of 105 dB and a DAC dynamic range of 108 dB under A-weighted conditions. Total Harmonic Distortion + Noise is specified at -92 dB for ADCs and -95 dB for DACs.

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Review the latest datasheet revision for any updates to absolute maximum ratings or electrical specifications. Ensure proper ESD handling procedures are followed during storage and installation to prevent damage to the sensitive internal circuitry.

Selection Notes

Select this component for applications requiring multiple independent stereo channels within a single integrated circuit. Consider the 52-lead MQFP package dimensions for PCB layout constraints. Evaluate power supply requirements, specifically the need for separate analog and digital supplies or ferrite bead isolation. Verify compatibility with the host processor's serial interface modes and clock frequency requirements before finalizing the design.
