Features
 Operates from V_CC = 2.5 to 5.5 V
 Dedicated standby mode active low for each
channel
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.
 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
