TCS7191B
GENERAL DESCRIPTION
The TCS7191B is a 2.8W high efficiency, non-clip,
filterless, Class-D audio power amplifier. It
operates from 2.7V to 5.5V supply. When
powered with 5V supply voltage, the TCS7191B is
capable of delivering 2.8W into 4Ω load or 1.65W
into 8Ω load, with THD+D less than 10%.
The TCS7191B features a non-clip output control,
which detects the output clipping caused by the
over-level input signal and automatically adjusts
the dynamic range of the output signal to prevent
the distortion of the audio signal. The non-clip
output control also eliminates the output clipping
due to a low battery supply voltage.
As a Class-D power amplifier, the TCS7191B features
high efficiency, up to 90%, and high PSRR, 75dB
at 217Hz, which make the device ideal for use in
battery-powered portable devices. It also features
minimized click-and-pop noise during turn-on and
turn-off transitions.
APPLICATIONS
Cellular handsets
Portable navigation devices
Multimedia internet devices
