MAX9725CEBC+TG45

Audio Amplifiers Overview

The MAX9725CEBC+TG45 is a fixed-gain stereo headphone amplifier from the DirectDrive series. It operates on 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 a -1V/V gain, 80dB PSRR at 1kHz, and ±8kV ESD protection. It includes integrated click-and-pop suppression, low-power shutdown (0.6µA), and short-circuit protection.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates DC-blocking capacitors by producing ground-referenced outputs
• Fixed -1V/V gain reduces external component count
• Integrated inverting charge pump creates negative supply for increased dynamic range
• Comprehensive click-and-pop suppression circuitry

Audio Amplifiers Applications

• MP3 Players
• Cellular Phones
• PDAs
• Smart Phones
• Portable Audio Equipment

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CEBC' against official documentation to confirm package type and temperature grade. Confirm lead-free status via RoHS compliance data. Check current lifecycle status as older variants may be discontinued. Ensure ordering information matches the exact manufacturer part number before procurement.

Audio Amplifiers Selection Notes

Select this model for applications requiring a fixed -1V/V gain without external feedback resistors. Suitable for space-constrained designs due to the UCSP package. Verify that the required output power aligns with the 20mW/channel specification at the target load impedance and supply voltage.

Audio Amplifiers Part Context

This component belongs to the MAX9725 family of 1V DirectDrive stereo headphone amplifiers. The family includes variants with different fixed gains (-2V/V, -1.5V/V, -4V/V) and an adjustable gain version. All share the same core architecture, operating voltage range, and package options.

Audio Amplifiers Replacement Considerations

Other MAX9725 variants (e.g., MAX9725AEBC+, MAX9725BEBC+) offer different fixed gains. If gain adjustment is acceptable, these are pin-compatible substitutes. For adjustable gain, the MAX9725E series is available.
