DESCRIPTION

· The DRV632 is a 2-V RMS pop-free stereo line driver designed for single-supply electronics, eliminating the need for output DC-blocking capacitors to reduce component count and cost.

· Utilizing TI’s DirectPath™ technology, it drives 2V RMS into a 10-kΩ load with a 3.3-V supply, featuring differential inputs and external gain-setting resistors for a gain range of ±1V/V to ±10V/V.

· It includes built-in active-mute control, external undervoltage detection for pop-free shutdown, and integrates a charge pump for a negative supply rail, ensuring a clean, ground-biased 2-V RMS output without requiring a split-rail power supply.

FEATURES

· Stereo DirectPath™ Audio Line Driver with 2Vrms into 10kΩ at 3.3-V supply.

· Low THD+N <0.01% at 2Vrms into 10kΩ and high SNR >90dB.

· 600-Ω output load compliant with differential input and single-ended output.

· Adjustable gain via external gain-setting resistors, low DC offset <1mV, and ground-referenced outputs eliminating DC-blocking capacitors.

· Features short-circuit protection, click- and pop-reduction circuitry, and active mute control for pop-free audio on/off control.

· Available in a space-saving 14-pin TSSOP package.

APPLICATIONS

· Set-Top Boxes, Blu-ray Disc™, DVD Players, LCD and PDP TVs.

· Mini/Micro Combo Systems, Sound Cards, Laptops.
