Technical content

The AN7158N is an integrated circuit designed for power amplifier of 7.5W (16V, 4Ω ) output with low noise and low distortion, and it suits TV set with multi-sound. Stereo operation is enabled due to incorporating two amplifiers on one chip. 12-pin SIL package enabled com- pact and high-densely mounted set. n Features

• Incorporating protection circuits (surge, thermal protec- tion and etc.)
• Automatic operating point stabilizer circuit
• Low distortion, low 1/f noise
• Low shock noise from power ON/OFF operation
• Better channel separation
• Fewer external components AN7158N Dual 7.5W Audio Power Amplifier Circuit 30.0–0.3 24.0–0.3 Unit : mm 1.26–0.25 1.8R 3.6–0.2 2.7–0.41.0–0.5 2.54 0.7–0.1 5.5–0.3 0.95–0.25 0.35–0.25 0.35 + 0.1 – 0.05 12-Lead SIP Package (HSIP012-P-0000B) n Block Diagram 5 6 3 V CC 7 10 Ch.2 Bootstrap GND Input Circuit Drive Output Circuit Over Voltage Protection Temperature Compensation Shock Noise Suppression Input Circuit Drive Over Voltage Protection Temperature Compensation Shock Noise Suppression Ch.1 Bootstrap Ch.2 Input Ch.1 Input Ch.2 Output Ch.1 Output GND Output Circuit
