TS2007FC Datasheet - STMicroelectronics

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.
