1 ANK Dual BTL W Audio Power Amplifier Overview The ANK is an integrated circuit for W (.V, Ω) output power amplifier circuit. Two BTL amplifiers are built-in on a single chip and stereo operation is possible. It is highly reliable due to protection circuits built-in. The built-in stand-by circuit makes it possible to switch the circuit ON/OFF with a charge mode to power supply pin. Features High output power (BTL W ) Stand-by circuit built-in Protection circuits built-in (temperature, overvoltage, V OUT short, Load short, V OUT V CC short) Low shock noise from power ON/OFF operation Fewer external parts Highly stable operation.±..±..±..±..±..±. ø..±..±..

Thermal breaking protection The protective operation starts at the chip temperature of C± C.. Overvoltage protection The protective operation starts at V CC V.. Ground fault protection The protective operation starts when the contact resistance dropped below.ω.. Load shortcircuit protection The protective operation starts when the contact resistance dropped below.ω.. Atmospheric fault protection The protective operation starts only when a shortcircuit between pins occurred.. TAB shortcircuit Even TAB short-circuiting with the potential causes no breaking trouble.. The operation remains normal even when the load is Ω.. When the chip temperature abnormally rose, the temperature protection circuit gets actuated, but it is automatically reset when the chip temperature dropped below the set level.
