Description

The TS2007 is a class D power audio amplifier. Able to drive up to 1.4 W into an 8 Ω load at 5 V, it achieves outstanding efficiency compared to typical class AB audio power amplifiers.

This device allows switching between two different gains: 6 or 12dB via a logic signal on the GS pin. A pop & click reduction circuitry provides low on/off switching noise while allowing the device to start within 5 ms. A standby function (active low) allows lowering the current consumption down to 10 nA typ.

The TS2007 is available in DFN8 3 x 3 mm lead-free packages.
