Description
The TS2007FC 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 better efficiency than
typical class AB audio power amplifiers.
This device can switch between two gain settings,
6 dB or 12 dB via a logic signal on the gain select
pin. Pop and click reduction circuitry provides low
on/off switch noise and allows the device to start
within 1 ms typically.

A standby mode function (active low) keeps the
current consumption down to 1 μA typical.
The TS2007FC is available in a 9-bump flip-chip
lead-free package.
