YOUDA INTEGRATED CIRCUIT
YD1028
18W CAR RADIO POWER AMPLIFIERYD1028
DESCRIPTION
The YD1028 is an integrated class-B dual output amplifier in a 9-lead single in-line (TO220Z9) plastic power
package. The device is primarily developed for car radio applications.
FEATURES
*Requires very few external components for Bridge Tied Load (BTL),Stereo or BTL application;
*High output power, Fixed gain, Good ripple rejection;
* Identical inputs (inverting and non-inverting),Low offset voltage at output (important for BTL);
*Mute/stand-by switch, No switch-on/switch-off plop;
*Load dump protection, AC and DC short-circuit-safe to ground and Vcc, Thermally protected;
*Reverse polarity safe;
*Capability to handle high energy on outputs (Vcc=0V);
*Protected against electrostatic discharge.
