Description
The TS4999 is a stereo fully-differential class D
power amplifier. It can drive up to 1.35 W into a
8
Ω
load at 5 V per channel. The device has four
different gain settings utilizing two discrete pins,
G0 and G1.
Pop and click reduction circuitry provides low
on/off switch noise while allowing the device to
start within 8 ms. 3D enhancement effects are
selected through one digital input pin that allows
more amazing stereo audio sound.
Two standby pins (active low) allow each channel
to be switched off separately.
The TS4999 is available in a flip chip, 18-bump,
lead-free package.
