TPA3200D1DCP

Audio Amplifiers Overview

The TPA3200D1DCP is a 20-W mono digital input audio amplifier from Texas Instruments. It operates with an 8 V to 18 V supply and drives loads as low as 4 Ω. The device accepts 16- to 24-bit data in I²S or 16-bit right-justified formats, featuring an 8x oversampling digital filter. Key electrical parameters include a typical efficiency of 85% into an 8 Ω load, a signal-to-noise ratio of 95 dB, and a total harmonic distortion plus noise of 0.2%. It includes three selectable fixed gain settings and operates within a -40 °C to 85 °C temperature range.

Audio Amplifiers Feature Summary

• Integrates a digital audio interface supporting I²S and 16-bit word right-justified formats with an internal 8x interpolation digital filter.
• Delivers high-efficiency Class-D operation that eliminates the need for external heat sinks under standard operating conditions.
• Includes comprehensive protection mechanisms such as thermal shutdown, short-circuit detection, and soft mute functionality.

Audio Amplifiers Applications

• Mono speaker systems requiring direct digital audio input
• Portable audio devices utilizing efficient power management
• Embedded audio solutions where thermal constraints limit heatsink usage

Audio Amplifiers Procurement Notes

Verify the specific package suffix DCP corresponds to the 44-pin HTSSOP variant. Confirm that the required system clock frequencies align with the supported sampling rates listed in the datasheet. Ensure that the design accounts for the PowerPAD thermal requirements and proper grounding of analog and digital sections to maintain specified performance levels.

Audio Amplifiers Selection Notes

Select this component when a single-channel digital amplifier is required with integrated filtering and modulation. It is suitable for designs prioritizing thermal efficiency and simplified analog front-end architecture. Consider the available gain settings and supply voltage range to ensure compatibility with the target speaker impedance and power source.

Audio Amplifiers Part Context

This part belongs to the TPA3200 family of digital audio amplifiers. It is designed to replace traditional analog amplifier stages by integrating the DAC and modulation functions directly on-chip. The device simplifies board layout by reducing the number of external components needed for signal processing and power amplification.

Audio Amplifiers Replacement Considerations

Check for the TPA3200D1DCPR variant if tape-and-reel packaging is required instead of the tube-packaged DCP version. Verify pinout compatibility if substituting with other members of the TPA3200 series, noting potential differences in gain configurations or control logic.
