MAX9850ETI+TGC1

Audio Amplifiers Overview

The MAX9850ETI+TGC1 is a stereo audio DAC with an integrated DirectDrive headphone amplifier. It operates on a single supply of 1.8V to 3.6V and supports sampling rates from 8kHz to 48kHz. The device provides 95mW output power into 16Ω at 3.0V and 30mW into 16Ω at 1.8V. It features a flexible digital interface supporting I2S, left-justified, and right-justified formats, along with an I2C-compatible control interface for volume and mute settings.

Audio Amplifiers Feature Summary

• DirectDrive technology eliminates the need for large DC-blocking capacitors by producing ground-biased analog outputs.
• Flexible clocking circuitry accepts any master clock up to 40MHz without requiring an external PLL.
• Stereo line inputs allow mixing of analog audio signals with the digital input stream.

Audio Amplifiers Applications

• MP3 and portable multimedia players
• Cell phones and smart phones
• Portable DVD players

Audio Amplifiers Procurement Notes

Verify the specific suffix TGC1 against official manufacturer documentation to confirm tape-and-reel packaging or temperature grade variations. Confirm lead-free status and RoHS compliance through current datasheets. Check component availability as product lifecycles may change.

Audio Amplifiers Selection Notes

Select this component for applications requiring space-constrained designs due to the elimination of output coupling capacitors. Ensure the system clock can support frequencies up to 40MHz. Verify that the required output power matches the available supply voltage range of 1.8V to 3.6V.

Audio Amplifiers Part Context

This part belongs to the MAX9850 series, which integrates a sigma-delta DAC and a Class AB headphone amplifier. The series is designed for portable electronics where board space and low power consumption are critical constraints. The DirectDrive architecture distinguishes it from traditional amplifiers requiring external components.

Audio Amplifiers Replacement Considerations

Consult official replacement lists for discontinued variants. Verify pin compatibility and electrical specifications before substituting with other audio DACs or amplifiers from the same manufacturer family.
