Texas Instruments DRV603 DirectPath 3‑VRMS Line Driver Adjustable Gain Handbook
The DRV603 is a 3‑VRMS pop‑free stereo line driver that eliminates the need for output DC‑blocking capacitors, reducing component count and cost. It is designed for single‑supply audio applications such as PDP/LCD‑TVs, Blu‑ray Disc players, set‑top boxes, and home‑theater systems.
Key features include DirectPath™ technology for pop‑free operation, low noise (SNR > 109 dB, THD+N < 0.002 %), adjustable gain from +1 V/V to +10 V/V via external resistors, differential inputs, and built‑in shutdown and undervoltage mute functions. The device operates from a 3.3 V or 5 V supply and provides up to 3 Vrms into a 2.5 kΩ load.
