MAX9723DEBE+T

Audio Amplifiers Overview

The MAX9723DEBE+T is a stereo DirectDrive headphone amplifier in a 16-bump UCSP package. It operates from a single 1.8V to 3.6V supply, delivering 62mW into a 16Ω load with 0.006% THD+N and 90dB PSRR. The device features integrated 32-level volume control, software-enabled BassMax, and I2C/SMBus interface. It includes industry-leading click-and-pop suppression, ±8kV HBM ESD protection, short-circuit and thermal-overload protection, and a low-power shutdown mode consuming 5μA.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates bulky DC-blocking capacitors by producing a ground-referenced output from a single supply.
• Integrated 32-level digital volume control and software-enabled BassMax boost accessible via I2C/SMBus-compatible interface.
• Comprehensive click-and-pop suppression circuitry ensures minimal audible transients during power-up and shutdown.
• Robust protection mechanisms include ±8kV HBM ESD-protected outputs, short-circuit protection, and thermal-overload protection.

Audio Amplifiers Applications

• PDA Audio
• Portable CD Players
• Mini Disc Players
• MP3-Enabled Cellular Phones
• MP3 Players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'DEBE+T' against the manufacturer's official ordering guide to confirm the exact slave address (MAX9723A/B/C/D), gain configuration, and tape-and-reel packaging status. Ensure compatibility with the target system's I2C bus voltage levels and check for any recent product discontinuance notifications or lifecycle changes directly from Analog Devices/Maxim Integrated documentation.

Audio Amplifiers Selection Notes

Select this component for space-constrained portable audio designs requiring high fidelity without external coupling capacitors. Choose based on the required maximum gain: MAX9723A/B offer 0dB max gain, while MAX9723C/D provide +6dB. Confirm the UCSP-16 package fits the PCB footprint and verify that the I2C address matches the system bus allocation to prevent conflicts with other peripherals.

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, enabling ground-referenced outputs. The DEBE+T variant specifically denotes the UCSP-16 package option, designed for extreme miniaturization in mobile devices where board area is at a premium compared to larger QFN packages.
