MAX9700CETB

Audio Amplifiers Overview

The MAX9700CETB 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 a supply voltage range of 2.5V to 5.5V. The device features low electromagnetic interference (EMI) through spread-spectrum modulation and operates without external output filters. It utilizes a differential input interface and is housed in a compact 10-TDFN package measuring 3x3mm. The component supports operation within a temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrated spread-spectrum modulation for minimized electromagnetic interference emissions
• Filterless design architecture eliminating the need for external output components
• Differential input configuration providing high noise immunity
• Built-in thermal protection and short-circuit current limiting

Audio Amplifiers Applications

• Portable media players and MP3 devices
• Mobile phones and handheld communication devices
• Personal digital assistants (PDAs)
• Small form-factor portable speakers

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CETB' against the official Maxim Integrated datasheet to confirm pinout compatibility and package dimensions. Ensure the source document explicitly lists this part number variant rather than generic family members. Confirm RoHS compliance status directly from the manufacturer's certification documents prior to integration.

Audio Amplifiers Selection Notes

Select this component when space constraints require a filterless Class-D solution with low EMI characteristics. The differential input is suitable for noisy digital environments common in mobile applications. Verify that the 1.2W output power meets the acoustic requirements of the target speaker impedance. Check availability as older Maxim products may have limited production runs or obsolescence notices.

Audio Amplifiers Part Context

This component belongs to the MAX9700 series of ultra-small, filterless Class-D audio amplifiers. The series is designed for battery-powered portable electronics requiring high efficiency and minimal board space. The CETB suffix denotes the specific TDFN-10 package variant within the broader MAX9700 product line.
