AD1986JSTZ-REEL

Overview

The AD1986JSTZ-REEL is an AC '97 2.3 compliant audio CODEC in a 48-pin LQFP package. It features six DAC channels for 5.1 surround sound and stereo ADCs with 20-bit resolution. The device supports variable sample rates from 7 kHz to 96 kHz, double-rate audio, and includes integrated headphone amplifiers. Key specifications include greater than 90 dB dynamic range, S/PDIF output, and an integrated parametric equalizer.

Feature Summary

• Integrated headphone amplifiers and dual independent outputs
• Advanced jack presence detection supporting up to eight jacks
• Internal microphone mixing and multiple VREF_OUT signals
• Software-controlled power management modes

Applications

• AC '97 compliant desktop and laptop motherboard audio subsystems
• 5.1 channel surround sound systems requiring integrated codecs
• Audio interfaces utilizing S/PDIF digital output capabilities

Procurement Notes

Verify the specific suffix JSTZ against the manufacturer's current ordering guide to confirm package type and tape-and-reel configuration. Ensure compatibility with the target system's AC '97 interface timing requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring AC '97 2.3 compliance with integrated headphone drivers. Consider the reduced support component count due to internal mixing and biasing features. Verify that the 48-pin LQFP package fits the PCB layout constraints.

Part Context

This part belongs to the Analog Devices AD198x series of high-performance audio CODECs. It is designed for PC audio applications, offering a balance of analog performance and digital integration within the AC '97 standard framework.

Replacement Considerations

Check for direct pin-compatible replacements within the AD198x family or newer AC '97 successors. Verify register-level compatibility if substituting with other manufacturers' AC '97 codecs.
