Low-power, Class-AB stereo driver for space-constrained applications
|
|
The TDA1308AUK from NXP is Class-AB stereo headphone driver housed in an 8-bump Wafer Level Chip Scale Package (WL-CSP) measuring only 0.61mm x 0.84mm x 0.38mm. The reduced footprint makes the driver ideal for use in space-constrained applications and portable products. |
The TDA1308AUK offers a
large output-signal swing and
excellent noise performance, and
delivers Class-AB stereo operation
from a single (2.4V to 7.0V) or dual (1.5V to
3.5V) range. The device operates over a wide
temperature range with
no switch on/off clicks.
Manufactured in a
1µm CMOS process,
the TDA1308AUK
also offers high
signal-to-noise
ratio, high slew
rate, and low
distortion. It has
a typical power
dissipation of
15mW (no load), 90dB
power-supply ripple
rejection at 100Hz, and
has built-in circuitry
that protects against
short circuits.
