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.
