Description
The demonstration board STEVAL-CCA008V1 is
made to evaluate the TS4998 that is designed for
top-class stereo audio applications. Thanks to its
compact and power-dissipation efficient QFN16
package with exposed pad, it suits a variety of
applications. With a BTL configuration, this audio
power amplifier is capable of delivering 1 W per
channel of continuous RMS output power into an
8 Ω load at 5 V.
Each output channel (left and right) also has its
own external controlled standby mode pin to
reduce the supply current to less than 10 nA per
channel. The device also features an internal
thermal shutdown protection. The gain of each
channel can be configured by external gain
setting resistors.
