Audio Amplifiers datasheet and documents for MAX9723CETE+

MAX9723CETE+

Audio Amplifiers Overview

The MAX9723CETE+ is a stereo DirectDrive headphone amplifier from Analog Devices/Maxim Integrated, designed for portable audio applications. It operates on a single 1.8V to 3.6V supply and delivers 62mW into a 16Ω load with 0.006% THD+N and 90dB PSRR. The device features integrated BassMax bass boost, 32-level digital volume control via I²C/SMBus, and industry-leading click-and-pop suppression. It consumes 3.7mA at 1.8V and includes ±8kV HBM ESD protection, short-circuit, and thermal-overload protection. Available in UCSP or TQFN packages.

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates bulky DC-blocking capacitors by generating a ground-referenced output from a single supply.
Integrated software-controlled BassMax circuitry boosts low-frequency response to compensate for inexpensive headphones.
Comprehensive click-and-pop suppression ensures minimal audible transients during power-up and shutdown transitions.
I²C/SMBus-compatible interface enables digital control of volume levels, gain settings, and shutdown modes.

Audio Amplifiers Procurement Notes

Verify the specific suffix 'ETE+' indicates the lead-free/RoHS-compliant Thin QFN package variant. Confirm the 'C' designation corresponds to the +6dB maximum programmable gain setting. Ensure the ordering code matches the required slave address configuration for system integration. Cross-reference the manufacturer's current production status as availability may vary.

Audio Amplifiers Selection Notes

Select this component when board space is limited due to its elimination of large output coupling capacitors. Choose the MAX9723CETE+ specifically if a higher maximum gain of +6dB is required compared to the 0dB variants. Ensure the application supports I²C communication for digital volume and feature control. Verify that the 1.8V to 3.6V supply range aligns with the system's battery voltage profile.

Audio Amplifiers Part Context

The MAX9723 belongs to Maxim Integrated's DirectDrive family of stereo headphone amplifiers. This series utilizes patented charge-pump technology to create an internal negative supply, allowing outputs to be biased at ground potential. The product line differentiates models primarily through I²C slave addresses and selectable maximum gain configurations, catering to diverse portable audio design requirements.
