DRV604PWP

Audio Amplifiers Overview

The DRV604PWP is a stereo line driver and headphone amplifier featuring DirectPath technology. It delivers 2Vrms output without requiring DC-blocking capacitors, reducing component count and cost. The device integrates adjustable gain and pop-free startup functionality. It operates on a single supply voltage within the -40°C to 85°C temperature range. Key electrical specifications include a signal-to-noise ratio exceeding 109dB and typical input voltage noise below 7µVrms across the 20Hz–20kHz bandwidth.

Audio Amplifiers Feature Summary

• DirectPath architecture eliminates the need for external DC-blocking capacitors at the output stage.
• Integrated pop-free circuitry prevents audible transients during power-up and power-down sequences.
• Adjustable gain configuration allows flexibility in system design and signal matching.

Audio Amplifiers Applications

• Single-supply portable audio devices
• Consumer electronics with strict size constraints
• Cost-sensitive audio subsystems

Audio Amplifiers Procurement Notes

Verify the package marking matches DRV604PWP exactly. Confirm the manufacturer is Texas Instruments. Check the datasheet for the specific pinout of the 28-pin HTSSOP package. Ensure the operating environment stays within the specified temperature range. Validate that the application requires the specific 2Vrms output capability.

Audio Amplifiers Selection Notes

Select this component when minimizing passive components is critical due to space limitations. Choose it for applications requiring high fidelity with SNR above 109dB. Consider it for single-supply designs where eliminating large coupling capacitors reduces board area. Verify that the required gain settings align with the adjustable gain options provided by the device architecture.
