Description
The TS2007 is a class D power audio amplifier.
Able to drive up to 1.4W into an 8 Ω load at 5V, it
achieves outstanding efficiency compared to
typical class AB audio power amplifier.
This device allows to switch between two different
gains: 6 or 12dB via a logic signal on the GS pin.
A pop & click reduction circuitry provides low
on/off switch noise while allowing the device to
start within 5ms. A standby function (active low)
allows to lower the current consumption down to
10nA typ.
