MAX9700BETB

Audio Amplifiers Overview

The MAX9700BETB is a single-channel, Class-D audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It delivers 1.6 W of output power into an 8-ohm load with a supply voltage range of 2.5 V to 5.5 V. The device features a fixed gain of 12 dB and achieves a total harmonic distortion plus noise (THD+N) of 0.01%. It operates within a temperature range of -40°C to +85°C and utilizes a 10-pin TDFN package.

Audio Amplifiers Feature Summary

• Incorporates spread-spectrum modulation to minimize electromagnetic interference emissions without requiring external output filters.
• Features differential inputs and comprehensive protection mechanisms including short-circuit and thermal overload safeguards.
• Supports synchronization via an external clock input to allow multiple units to operate in stereo configurations.

Audio Amplifiers Applications

• Portable digital audio players
• Mobile communication devices
• Compact multimedia systems

Audio Amplifiers Procurement Notes

Verify the specific suffix ETB against official datasheets to confirm pinout compatibility and gain settings. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status as distribution channels may vary. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Audio Amplifiers Selection Notes

Select this model when low EMI radiation is critical and space constraints prohibit traditional filter components. The 12 dB internal gain suits applications requiring moderate signal amplification. Evaluate the TDFN package for thermal management needs in enclosed designs. Consider the SYNC pin functionality if synchronizing multiple amplifiers in a system.

Audio Amplifiers Part Context

This component belongs to the MAX9700 family of filterless Class-D audio amplifiers. Variants such as MAX9700A, C, and D offer different fixed gains ranging from 6 dB to 20 dB. The family shares core architecture but differs in gain settings and packaging options like UCSP or uMAX.

Audio Amplifiers Replacement Considerations

Direct substitutes include other MAX9700 variants with adjusted gain settings, such as MAX9700DETB for 20 dB gain. Verify package dimensions and pin assignments before substitution. Alternative families require evaluation of efficiency and EMI performance characteristics.
