AD1988BJSTZ

Overview

The AD1988BJSTZ is a high-performance audio codec manufactured by Analog Devices Inc., designed for professional and consumer audio applications. It integrates two stereo analog-to-digital converters (ADCs) and four stereo digital-to-analog converters (DACs). The device supports sampling rates up to 24-bit resolution at frequencies of 48 kHz, 96 kHz, and 192 kHz. It operates on a single 3.3 V power supply with separate analog and digital domains. The component utilizes a serial interface for data transfer and control, housed in a 48-lead LQFP package suitable for surface-mount assembly.

Feature Summary

• Integrates dual stereo ADCs and quad stereo DACs within a single chip
• Supports high-resolution 24-bit audio conversion across multiple sample rates
• Includes integrated clock generator and jitter attenuator for signal integrity
• Features low-power operation with dedicated standby modes

Applications

• Professional audio recording interfaces
• High-fidelity home theater systems
• Digital audio workstations and mixing consoles
• Multimedia PCs and sound cards

Procurement Notes

Verify the specific suffix 'BSTZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure that the required operating temperature range matches the 'J' grade specifications. Cross-reference the package dimensions with your PCB footprint library before finalizing procurement orders to avoid mechanical mismatches.

Selection Notes

Select this component when designing systems requiring multiple independent audio channels with high dynamic range. Compare performance metrics such as total harmonic distortion and signal-to-noise ratio against alternative codecs if strict acoustic purity is required. Consider the available I2S or TDM interface options for integration with your chosen digital signal processor or microcontroller.

Part Context

This part belongs to the AD198x series of audio codecs from Analog Devices. It shares architectural similarities with other members like the AD1988 but differs in package type and specific electrical characteristics defined by the suffix. The series is widely recognized for balancing high audio fidelity with cost-effective integration in multi-channel audio solutions.

Replacement Considerations

Check for direct substitutes such as the AD1988BSTZ or AD1988BRMZ depending on package requirements. Verify functional equivalence regarding pin assignments and register maps before swapping components in existing designs.
