TPA3200D1DCPG4

Audio Amplifiers Overview

The TPA3200D1DCPG4 is a 20-W mono digital input audio amplifier from Texas Instruments. It operates with supply voltages (PVCC, VCC) ranging from 8 V to 18 V and a digital supply (VDD) of 4.5 V to 5.5 V. The device delivers 20 W into an 8-Ω load at 18 V and 12.8 W into a 4-Ω load at 12 V. It accepts 16-bit right-justified or I²S data formats with sampling frequencies between 5 kHz and 200 kHz. Total harmonic distortion plus noise is typically 0.2% at 10 W output. The component utilizes a 44-pin DCP package.

Audio Amplifiers Feature Summary

• Integrates a digital interface supporting I²S and 16-bit word right-justified formats with an internal 8x interpolation digital filter.
• Features high efficiency operation that eliminates the need for external heat sinks during standard music playback.
• Includes comprehensive protection mechanisms such as thermal shutdown and latched short-circuit detection on outputs.

Audio Amplifiers Applications

• Driving bridged-tied mono speakers in consumer audio equipment
• Digital audio systems requiring efficient power amplification without external heatsinks
• Applications utilizing single-supply voltage ranges from 8 V to 18 V

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix PG4 indicates lead-free and RoHS compliance status against current manufacturer documentation. Confirm the DCP package type matches the required PCB footprint and thermal pad soldering requirements. Ensure the digital supply voltage aligns with the 4.5 V to 5.5 V specification for proper logic level compatibility.

Audio Amplifiers Selection Notes

Select this component for designs requiring a fully digital Class-D amplifier solution with integrated filtering. It is suitable for applications where board space is limited due to the elimination of external heat sinks. Consider the fixed gain options available via hardware pins when designing the preceding signal chain stages.

Audio Amplifiers Part Context

This part belongs to the TPA3200D1 series of digital audio power amplifiers. It is designed for mono speaker driving configurations using a bridged-tied load topology. The device integrates the digital-to-analog conversion and modulation stages directly within the amplifier IC.

Audio Amplifiers Replacement Considerations

The TPA3200D1DCPR is the tape-and-reel version of this component. Verify pinout and electrical specifications match before substituting other Class-D amplifiers.

Audio Amplifiers FAQ

What digital audio formats does the TPA3200D1 support?

The device supports standard I²S format (16- to 24-bit) and 16-bit word right-justified format, selectable via the FORMAT pin.

How is the amplifier gain configured?

Gain is set by two hardware pins, GAIN0 and GAIN1, providing three selectable fixed gain settings: 12 dB, 18 dB, and 23.6 dB.
