The DRV632PWR is a high-performance stereo headphone amplifier developed by Texas Instruments for portable and battery-powered audio applications. It integrates two high-current output channels capable of driving low-impedance headphone and speaker loads with very low total harmonic distortion and noise (THD+N).
Based on a fully differential amplifier topology, the DRV632PWR eliminates the need for large output coupling capacitors and provides excellent common-mode noise rejection. This architecture helps improve audio fidelity, reduce PCB area and simplify system design, especially in compact consumer electronics.
Operating from a single supply voltage as low as 3 V, the device achieves an optimal balance between output power and efficiency. Its low quiescent current and wide bandwidth make it suitable for smartphones, tablets, portable media players and other audio-enabled embedded systems.
The DRV632PWR delivers low distortion performance with a typical THD+N of 0.002% at 1 kHz. This ensures clean audio reproduction across the audible frequency range, even when driving low-impedance loads.
Differential outputs provide improved noise immunity and eliminate output DC blocking capacitors. This reduces component count, lowers system cost and improves signal integrity in noisy environments.
With a typical quiescent current of only 14 mA, the device supports extended battery life while maintaining strong output drive capability for headphones and small speakers.
The TSSOP-8 package enables compact PCB layouts and easy integration into space-constrained consumer and portable electronics designs.
A small-signal bandwidth of up to 8 MHz ensures accurate transient response and minimal phase distortion, preserving audio detail and clarity.
A typical slew rate of 4.5 V/µs allows the amplifier to handle fast signal changes without audible distortion or signal compression.
The DRV632PWR is designed to operate reliably over a wide temperature range from −40 °C to +85 °C, supporting consumer and automotive cabin environments.
