Features

 Operates from VCC = 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
