3 Description
The DRV612 is a single-ended, 2-Vrms stereo line
driver designed to reduce component count, board
space, and cost. It is ideal for single-supply
electronics where size and cost are critical design
parameters.
The DRV612 does not require a power supply greater
than 3.3 V to generate its 5.6-VPP output, nor does it
require a split-rail power supply.
The DRV612 device is designed using TI’s patented
DirectPath technology, which integrates a charge
pump to generate a negative supply rail that provides
a clean, pop-free ground-biased output. The DRV612
is capable of driving 2 Vms into a 600-Ω load.
DirectPath technology also allows the removal of the
costly output dc-blocking capacitors.
The device has fixed-gain single-ended inputs with a
gain-select pin. Using a single resistor on this pin, the
designer can choose from 13 internal programmable
gain settings to match the line driver with the codec
output level. The device also reduces the component
count and board space.
Line outputs have ±8-kV HBM ESD protection,
enabling a simple ESD protection circuit. The
DRV612 has built-in active mute control with more
that 80-dB attenuation for pop-free mute on/off
control.
The DRV612 is available in a 14-pin TSSOP and 16-
pin VQFN. For a footprint-compatible stereo
headphone driver, see the TPA6139A2.
