DRV632PWR

Audio Special Purpose Overview

The DRV632PWR is a stereo DirectPath audio line driver from Texas Instruments, housed in a 14-TSSOP package. It delivers 2 Vrms into a 10 kΩ load with a 3.3-V supply and supports gains of ±1 V/V to ±10 V/V via external resistors. Key electrical parameters include a THD+N of 90 dB, output offset voltage under 1 mV, and an operating temperature range of -40°C to 85°C. The device operates on a single 3 V to 3.6 V supply, utilizing an internal charge pump to generate a negative rail for ground-referenced outputs.

Audio Special Purpose Feature Summary

• DirectPath technology eliminates the need for output DC-blocking capacitors
• Integrated charge pump generates negative supply rail for single-supply operation
• Active mute control provides pop-free audio on/off switching
• External undervoltage detection ensures safe shutdown without pops

Audio Special Purpose Applications

• Set-Top Boxes
• Blu-ray Disc and DVD Players
• LCD and PDP TVs
• Mini/Micro Combo Systems
• Sound Cards and Laptops

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the 14-TSSOP package and Tape & Reel packaging format. Confirm that the component meets the required RoHS compliance standards for your manufacturing process. Ensure the supplier provides valid traceability documentation for production-grade semiconductor devices.

Audio Special Purpose Selection Notes

Select this component when designing single-supply audio systems requiring high output voltage swing without split rails. The adjustable gain range allows flexibility for various DAC output levels. Consider the 14-TSSOP footprint for space-constrained PCB layouts. Verify that input blocking capacitors are sized correctly to maintain low-frequency response alongside the chosen gain-setting resistors.

Audio Special Purpose Part Context

The DRV632 belongs to TI's DirectPath family of audio line drivers. It shares architectural similarities with the DRV612 and DRV603 but offers specific gain and offset characteristics tailored for consumer audio applications. The 'PWR' suffix specifically denotes the TSSOP physical package variant within this product line.

Audio Special Purpose Replacement Considerations

The DRV612PWR serves as a functional substitute within the same series, offering similar DirectPath architecture and pinout compatibility. Designers should verify that the gain settings and offset voltage specifications of the replacement part align with the original circuit requirements before implementation.
