AD1886AJSTZ

Overview

The AD1886AJSTZ is a 16-bit stereo full-duplex AC'97 codec manufactured by Analog Devices. It integrates two 16-bit analog-to-digital converters and two digital-to-analog converters with multibit architecture, achieving greater than 90 dB dynamic range. The device features four stereo line-level inputs (LINE-IN, CD, VIDEO, AUX), two mono inputs for speakerphone and PC BEEP, and a microphone input with a switchable 20 dB preamplifier. Outputs include stereo line-level drivers, a dedicated stereo headphone amplifier, and a mono output. It supports variable sample rates from 7040 Hz to 48 kHz, SPDIF output, and operates on split power supplies of 3.3 V digital and 5.0 V analog.

Feature Summary

• AC'97 2.2 compliant interface supporting variable sample rate audio generation
• Integrated stereo headphone amplifier with software-controlled volume and mute functions
• Multibit DAC architecture providing high signal-to-noise ratio and low distortion
• Built-in jack sense capability for automatic output switching between line and headphone outputs

Applications

• Desktop and laptop computer audio subsystems
• Telephony systems requiring speakerphone functionality
• Consumer electronics utilizing AC'97 bus architectures

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the operating environment remains within the specified temperature range of 0°C to 70°C. Confirm that the system design accommodates the required split power supply voltages of 3.3 V for digital logic and 5.0 V for analog circuits prior to integration.

Selection Notes

Select this component when an AC'97 2.2 compliant solution is required for desktop or mobile platforms. It is suitable for designs needing integrated stereo headphone amplification and multiple analog inputs without external mixers. Verify that the application requires 16-bit resolution and does not necessitate higher bit-depth ADC/DAC performance found in premium audio codecs.

Part Context

This part belongs to the AD1886A series of AC'97 codecs designed for general-purpose computing audio applications. The 'JSTZ' suffix indicates a commercial temperature range variant packaged in a 48-lead Thin Quad Flatpack (LQFP). It serves as a direct replacement for legacy AC'97 implementations requiring integrated analog front-end processing.
