DESCRIPTION
The DRV601 is a 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 DRV601 is capable of driving 2 Vrms into a 600-Ω load at 3.3 V. The device has external gain setting
resistors, that support a gain range of -1V/V to -10V/V, and line outputs that has ±8-kV IEC ESD protection. The
device has independent shutdown control for the right and left audio channels.
The DRV601 is available in a 4 mm
×
4 mm Thin QFN package.
