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.
