DRV604PWPR

Audio Amplifiers Overview

The DRV604PWPR is a stereo line driver with integrated headphone amplifier utilizing DirectPath technology. It delivers 2Vrms output into a 5kΩ load and provides 40mW into a 32Ω headphone load at 3.3V. Key electrical parameters include a signal-to-noise ratio exceeding 109dB, typical noise voltage below 7µVrms (20Hz–20kHz), and total harmonic distortion plus noise under 0.002% at 10kΩ. The device operates on a single supply, eliminating the need for output DC blocking capacitors.

Audio Amplifiers Feature Summary

• DirectPath architecture removes output DC blocking capacitors to reduce component count and PCB area.
• Integrated pop-and-click suppression circuitry prevents audible noise during power-up and signal switching.
• Built-in undervoltage lockout monitors supply voltage to prevent upstream DAC artifacts.
• Short-circuit and thermal protection mechanisms ensure operational reliability under fault conditions.

Audio Amplifiers Applications

• Single-supply portable audio devices requiring compact form factors
• Smartphones and mobile communication handsets
• Portable media players and digital audio recorders
• Laptop computers and tablet PCs

Audio Amplifiers Procurement Notes

Verify the complete part number DRV604PWPR against official Texas Instruments documentation to confirm the PWPR suffix indicates the specific tape-and-reel packaging configuration. Ensure compatibility with the target application's voltage requirements and signal integrity standards before finalizing procurement decisions.

Audio Amplifiers Selection Notes

Select this component when design constraints prioritize minimal external passive components and low power consumption in single-supply environments. The DirectPath technology is suitable for applications where space savings from removing large coupling capacitors are critical. Verify that the required output voltage swing and headphone drive capabilities meet the specific transducer impedance requirements of the end product.

Audio Amplifiers Part Context

This device belongs to the DRV60x family of high-performance audio drivers. It shares the core DirectPath technology found in related models but offers specific integration of stereo line driving and headphone amplification. The family targets consumer electronics manufacturers seeking to simplify analog audio front-ends while maintaining high fidelity specifications.

Audio Amplifiers Replacement Considerations

Consult official substitution guides for compatible alternatives within the DRV series. Verify pinout compatibility and electrical parameter equivalence if replacing existing designs. Do not assume functional interchangeability with other audio amplifier families without detailed datasheet comparison.
