Frequently Asked Questions
What is the primary function of the DRV603?
It is a popp-free stereo line RMS driver designed to generate a clean, pop-free 3V output while significantly reducing component count.
Does the DRV603 require a split-rail power supply?
No, it can generate its required output up to 8.5V using only a 5V supply voltage, eliminating the need for a split-rail system.
What is the minimum load impedance requirement for the DRV603?
The minimum specified load impedance (I SS) must be greater than 600 Ohms.
How does the device handle low voltages or transients?
It features an internal undervoltage detector that provides an external Undervoltage Mute output to mute the signal when the supply voltage is too low.
