1 / 31 page  April 2008 Rev 3 1/31 31 TS2012FC Filter-free flip-chip stereo 2x2.5 W class D audio power amplifer Features ■ Operates from VCC= 2.5 V to 5.5 V ■ Dedicated standby mode active low for each channel ■ Output power per channel: 1.15 W @5 V or 0.63 W @ 3.6 V into 8 Ω with 1% THD+N max. ■ Output power per channel: 1.85 W @5 V into 4 Ω with 1% THD+N max. ■ Output short-circuit protection ■ Four gain setting steps: 6, 12, 18, 24 dB ■ Low current consumption ■ PSSR: 63 dB typ @ 217 Hz. ■ Fast startup phase: 7.8 ms ■ Thermal shutdown protection ■ Flip-chip 16-bump lead-free package Applications ■ Cellular phone ■ PDA Description The TS2012 is a fully differential stereo class D power amplifier able to drive up to 1.15 W into an 8 Ω load at 5 V per channel. It achieves better efficiency compared to typical class AB audio amps. The device has four different gain settings utilizing 2 digital pins: G0 and G1. Pop and click reduction circuitry provides low on/off switch noise while allowing the device to start within 8 ms. Two standby pins (active low) allow each channel to be switched off separately. The TS2012 is available in a flip-chip 16-bump lead-free package.
