Audio line driver for single-ended stereo paths
The Texas Instruments DRV632PW is a 2-channel analog line driver from the DirectPath™ series, designed for pre-amplifier and consumer audio applications. It operates from a 3V to 3.6V supply rail and delivers single-ended outputs, making it a direct fit for battery-powered or low-voltage audio gear where a clean analog signal path is needed before a headphone amp, codec line-in, or external amplifier stage. The 14-TSSOP package keeps the footprint compact for mixed-signal PCBs where board area is tight.
Supply rail and temperature — what they mean for the BOM
The 3V to 3.6V supply range ties this part directly to 3.3V audio rails — common in portable codecs, USB-audio bridges, and DSP-based pre-amps. There is no headroom for a 5V rail, so verify the analog supply regulator before committing the BOM. The -40°C to 85°C industrial temperature grade covers consumer and pro-audio equipment in indoor and outdoor-ventilated enclosures, but not under-hood automotive or extended industrial environments beyond 85°C ambient.
Lifecycle and sourcing note
The DRV632PW carries an Active product status with ROHS3 compliance.
