AD1836ACS

Overview

The AD1836ACS is a high-performance, single-chip audio codec manufactured by Analog Devices Inc. It integrates three stereo digital-to-analog converters (DACs) and two stereo analog-to-digital converters (ADCs) utilizing a multibit Sigma-Delta architecture. The device supports 24-bit resolution and sample rates up to 96 kHz. It operates from a single 5 V supply with provisions for separate output supplies to interface with low-voltage external circuitry. Key electrical specifications include an ADC signal-to-noise ratio of 105 dB and a DAC signal-to-noise ratio of 108 dB. The component features a flexible serial data port compatible with I2S and DSP modes, housed in a 52-lead MQFP package.

Procurement Notes

Verify the specific suffix 'C' against official Analog Devices documentation to confirm temperature range and package variant accuracy. Ensure compatibility with existing system power supplies and serial interface protocols before integration. Cross-reference part numbers with current manufacturer catalogs as legacy components may have updated revisions or end-of-life statuses.

Selection Notes

Select this component for applications requiring high-fidelity multi-channel audio conversion within a single integrated circuit. Consider the 52-lead MQFP package size and thermal characteristics during PCB layout. Verify that the host microcontroller supports the required SPI or serial port modes for configuration and data transfer.

Part Context

The AD1836A series belongs to Analog Devices' portfolio of multichannel audio codecs designed for professional and consumer audio applications. This specific model utilizes Sigma-Delta modulation to achieve high dynamic range performance. It is part of a family that includes variants with different packaging or temperature ratings, serving as a core solution for complex audio routing and processing tasks.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts.
