1 / 28 page August 2008 Rev 1 1/28 28 TS2007FC 3 W filter-free class D audio power amplifier with 6 or 12 dB fixed gain select Features ■ Operates from VCC=2.4 V to 5.5 V ■ Standby mode active low ■ Output power: 1.4 W at 5 V or 0.5 W at 3.0 V into 8 Ω with 1% THD+N max. ■ Output power: 2.3 W at 5V or 0.75 W at 3.0 V into 4 Ω with 1% THD+N max. ■ Two fixed gain selects: 6 dB or 12 dB ■ Low current consumption ■ Efficiency: 86% typical ■ Signal-to-noise ratio: 90 dB typical ■ PSRR: 68 dB typical at 217 Hz with 6 dB gain ■ PWM base frequency: 280 kHz ■ Low pop and click noise ■ Thermal shutdown protection ■ Output short-circuit protection ■ Flip-chip lead-free 9-bump package with back coating in option. Applications ■ Cellular phone ■ PDA ■ Notebook PC 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.
