MAX9700AEBC-T

Audio Amplifiers Overview

The MAX9700AEBC-T is a single-channel, Class D audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It delivers 1.2W of output power into an 8-ohm load with efficiency exceeding 90%. The device operates on a supply voltage range of 2.5V to 5.5V and features a fixed gain of 6 dB. Key electrical specifications include a Total Harmonic Distortion plus Noise (THD+N) of 0.01%, a Signal-to-Noise Ratio (SNR) above 90 dB, and a Power Supply Rejection Ratio (PSRR) of 72 dB at 217 Hz. It utilizes a 12-ball UCSP package and functions within a temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Low-Electromagnetic Interference (EMI) operation using spread-spectrum modulation to reduce radiated emissions without external filters.
• Filterless design architecture that eliminates the need for output LC filters, saving board space and reducing system cost.
• Integrated protection mechanisms including thermal shutdown and short-circuit protection to ensure device reliability.
• Ultra-low quiescent current and dedicated low-power shutdown mode to extend battery life in portable applications.

Audio Amplifiers Applications

• Portable media players and MP3 devices
• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• Laptop computers and notebooks

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Check for End-of-Life (EOL) status or last-time-buy notifications, as this part may be discontinued or subject to limited availability. Ensure compliance with RoHS directives if environmental regulations apply to the final product.

Audio Amplifiers Selection Notes

Select this component when a filterless Class D solution is required to minimize electromagnetic interference in compact designs. The 6 dB internal gain suits applications where the input signal amplitude is sufficient without additional amplification. Consider the 12-ball UCSP package for tight footprint constraints. Evaluate the 1.2W power rating against the specific speaker impedance and desired volume levels to ensure adequate headroom.

Audio Amplifiers Part Context

This device belongs to the MAX9700 family of low-EMI, filterless Class D audio amplifiers. It shares architectural similarities with other Maxim Integrated audio solutions but is distinct in its specific gain configuration and package type. The family focuses on eliminating output filters while maintaining high audio fidelity and efficiency, targeting the mobile consumer electronics market.
