Description
The TS2007 is a class D power audio amplifier. Able to drive up to 1.4W into an 8 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. The TS2007 is available in DFN8 3x3mm leadfree packages.
