DRV601 is a stereo line driver produced by TI. Its feature is that the gain can be set by external resistors and supports a gain range of -1V/V to -10V/V.
The DRV601 stereo line driver eliminates the need for output dc‑blocking capacitors, reducing component count and board area. It operates from a single supply (1.8 V‑4.5 V) and delivers up to 2 Vrms into a 600 Ω load.
Key features include independent right and left channel control, external gain‑setting resistors (‑1 V/V to ‑10 V/V), +8 kV IEC ESD protection, and shutdown control for each channel. The device is offered in a 20‑pin 4 mm × 4 mm Thin QFN package with a thermally‑enhanced PowerPAD™ design.
