General Description
G1421 is a stereo audio power amplifier in 24pin
TSSOP thermal pad package. It can drive 1.8W con-
tinuous RMS power into 4
Ω load per channel in
Bridge-Tied Load (BTL) mode at 5V supply voltage. Its
THD is smaller than 1% under the above operation
condition. To simplify the audio system design in the
notebook application, G1421 supports the Bridge-Tied
Load (BTL) mode for driving the speakers, Single-End
(SE) mode for driving the headphone. In the HP-IN
mode, it can support a DC value to the phone-jacket
and drive the headphone without the audio amplifier
outputs coupling capacitors. G1421 can mute the out-
put when Mute-In is activated. For the low current
consumption applications, the SHDN mode is sup-
ported to disable G1421 when it is idle. The current
consumption can be further reduced to below 5A.
G1421 also supports two input paths, that means two
different gain loops can be set in the same PCB and
choosing either one by setting HP/
LINE pin. It en-
hances the hardware designing flexibility. G1421 also
supports an extra function -- the maximum output
power clamping function to protect the speakers or
headphones from burned-out.
