The DRV603PW is a 3-VRMS pop-free stereo line driver designed to allow the removal of the output dc-blocking capacitors for reduced component count and cost. The device is ideal for single-supply electronics where size and cost are critical design parameters.
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.
| Output voltage (3.3 V supply) | 2 Vrms into 2.5 kΩ load |
|---|---|
| Output voltage (5 V supply) | 3 Vrms into 2.5 kΩ load |
| Signal‑to‑noise ratio | > 109 dB |
| Total harmonic distortion + noise | < 0.002 % |
| Supply voltage range | 0.3 V to 5.5 V |
| Minimum load impedance | > 600 Ω |
| Typical input noise voltage | < 7 µV rms |
| Charge‑pump frequency | 225 kHz to 675 kHz |
| External undervoltage detection threshold | 1.25 V |
| Package | 14‑pin TSSOP |
It delivers 2 Vrms into a 2.5 kΩ load when powered from 3.3 V.
No, the device integrates its own charge pump to generate a negative supply rail, allowing operation from a single supply.
The DRV603 achieves a signal‑to‑noise ratio greater than 109 dB.
The DRV603 is offered in a 14‑pin TSSOP package.
