TPA3200D1DCPR

Audio Amplifiers Overview

The TPA3200D1DCPR is a 20-W mono digital input audio amplifier manufactured by Texas Instruments. It operates with an analog supply voltage (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 12 V and supports load impedances as low as 4 Ω. It accepts 16-bit to 24-bit audio data in I²S or 16-bit word right-justified formats with sampling frequencies between 5 kHz and 200 kHz. Key electrical parameters include a typical signal-to-noise ratio of 95 dB, 0.2% THD+N at 10 W output, and three selectable fixed gain settings: 12 dB, 18 dB, and 23.6 dB.

Audio Amplifiers Feature Summary

• Integrates a digital interface supporting I²S and 16-bit word right-justified formats with an internal 8x oversampling digital filter.

Audio Amplifiers Applications

• Driving bridged-tied speakers with impedances down to 4 Ω
• Digital audio systems requiring efficient Class-D amplification without external heat sinks

Audio Amplifiers Procurement Notes

Verify the specific suffix 'R' indicates the tape-and-reel packaging variant of the DCP package. Confirm that the operating temperature range aligns with system requirements, as the device is rated for -40 °C to 85 °C. Ensure the power supply voltages remain within the specified 8 V to 18 V limits for PVCC/VCC and 4.5 V to 5.5 V for VDD to maintain performance and reliability.

Audio Amplifiers Selection Notes

Select this component for applications requiring a single-channel digital audio amplifier with high efficiency. The integrated digital filter simplifies pre-amplifier design by accepting standard serial audio interfaces. Consider the thermal dissipation characteristics of the PowerPAD package when designing for high-power outputs or elevated ambient temperatures.

Audio Amplifiers Part Context

This part belongs to the TPA3200D1 series of digital audio power amplifiers. It utilizes a 44-pin DCP (PowerPAD) package designed for thermally enhanced performance. The device is intended for driving speakers efficiently while minimizing external component count through integrated protection and filtering features.

Audio Amplifiers Replacement Considerations

The TPA3200D1DCP is the lead-free tube version of this device. Verify pin compatibility and thermal requirements when substituting between reel and tube packages.
