April 2014 DocID026152 Rev 1 1/32 TS2012EI Filter-free Flip Chip stereo 2 x 2.5 W class D audio power amplifier Datasheet - production data Features Operates from V CC = 2.5 to 5.5 V Dedicated standby mode active low for each channel Output power per channel: 1.15 W at 5 V or 0.63 W at 3.6 V into 8 with 1% THD+N max. Output power per channel: 1.85 W at 5 V into 4 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. at 217 Hz. Fast startup phase: 7.8 ms Thermal shutdown protection Flip Chip 16 bump lead-free package Applications Cellular phones PDA Description The TS2012EI is a fully-differential stereo class D power amplifier able to drive up to 1.15 W into an 8 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 two 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 TS2012EI is available in a Flip Chip 16 bump lead-free package.
