ADAU1373BCBZ-RL

Overview

The ADAU1373BCBZ-RL is a low power stereo audio codec with integrated digital audio processing. It supports stereo 48 kHz record and playback, with ADCs and DACs handling sampling rates from 8 kHz to 48 kHz. The device features eight single-ended or four differential analog inputs with programmable gain amplifiers (PGAs) providing -12 dB to +18 dB gain adjustment. It includes two stereo digital microphone inputs, three serial digital audio ports with asynchronous sample rate converters (ASRCs), and an I²C control interface. Power consumption is 7 mW for recording and 6 mW for playback at 48 kHz and 1.8 V.

Feature Summary

• Integrated Class-G headphone amplifier and filterless Class-D speaker amplifier
• Built-in fixed function DSP for equalization and dynamic range control
• Flexible analog input/output mixers and routing options
• Support for multiple digital audio interfaces including I²S and PCM

Applications

• Mobile phones
• Tablet PCs
• E-books
• Portable media players

Procurement Notes

Verify the specific ordering suffix BCBZ-RL against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and interface protocols before finalizing procurement orders.

Selection Notes

Select this component when a compact solution combining high-quality audio conversion with onboard signal processing is required. The integrated DSP reduces external processor load, while the low power consumption makes it suitable for battery-operated portable devices requiring extended usage time.

Part Context

This part belongs to the Analog Devices ADAU1373 series of low power audio codecs. It is designed specifically for mobile applications where space and power efficiency are critical constraints. The integration of amplifiers and DSP allows for simplified board layouts compared to discrete solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family that may offer updated packaging or minor feature enhancements. Verify electrical parameters and software compatibility if substituting with other audio codec models.
