MAX9725CEBC+T

Audio Amplifiers Overview

The MAX9725CEBC+T is a fixed-gain, stereo headphone amplifier utilizing DirectDrive architecture to eliminate DC-blocking capacitors. It operates from a single 0.9V to 1.8V supply and delivers up to 20mW per channel into a 32Ω load with 0.006% THD+N. The device features an inverting charge pump for ground-referenced outputs, ±8kV ESD protection, and integrated click-and-pop suppression. It includes a low-power shutdown mode reducing current to 0.6µA and short-circuit protection. The unit is housed in a 12-bump UCSP package.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates the need for large DC-blocking output capacitors by generating a negative internal supply via an inverting charge pump.
• Fixed gain of -1V/V reduces external component count compared to adjustable variants.
• Integrated comprehensive click-and-pop suppression circuitry prevents audible transients during startup and shutdown.
• Low quiescent current consumption allows direct operation from a single AA or AAA battery cell.

Audio Amplifiers Applications

• Portable audio equipment
• Cellular phones
• Smart phones

Audio Amplifiers Procurement Notes

Verify the specific suffix 'C' indicates the fixed -1V/V gain configuration upon procurement. Confirm the '+T' designation corresponds to tape and reel packaging. Ensure the component meets RoHS compliance standards as indicated by the lead-free marking. Cross-reference the manufacturer's ordering information to validate availability status.

Audio Amplifiers Selection Notes

Select this model when a fixed -1V/V gain is required for stereo headphone driving applications. The DirectDrive technology is suitable for designs prioritizing board space savings by removing output coupling capacitors. Verify that the application environment remains within the specified -40°C to +85°C operating temperature range.

Audio Amplifiers Part Context

This component belongs to the MAX9725 family of low-power, DirectDrive stereo headphone amplifiers manufactured by Analog Devices / Maxim Integrated. The family includes variants with different fixed gains (-2V/V, -1.5V/V, -4V/V) and an adjustable gain version (MAX9725E). All variants share the same core architecture and package options.
