2-VRMS audio line driver ICs for better audio quality

The new DRV603 line driver from Texas Instruments integrates under voltage protection (UVP) to monitor the supply rail and mute outputs before the rest of the system loses power. Through this feature click and pop noise are eliminated to ensure clear audio.

Key features of the DRV602 and DRV603 are,

1. 2-VRMS output even with 3.3-V power supply
2. Differential inputs
3. Ground reference outputs
4. Variable input gain
5. 106.5 dB SNR (DRV602) and >109 dB SNR (DRV603)

Package: 2 channel: QFN
4 channel: TSSOP

Price: Depending on the channel count these devices are priced in the range of $0.85 each to $4.60 for 1K pieces
