AB Audio Power Ic


STK404-130S 1 CH AB AUDIO POWER IC

€

Features

• Compact packaging supports slimmer set designs (30W to 120 W)

• Series designed for 30 up to 80 W (100 W) and pincompatibility (100 to 120 W have 18 pins)

• Simpler heat sink design facilitates thermal design of slim stereo sets

• Current mirror circuit application reduces distortion to 0.08%

• Supports addition of electronic circuits for thermal shutdown and load-short protection circuit as well as pop noise muting which occurs when the power supply switch is turned on and off

Description of External Parts

R1, C1 : Input filter circuit

• Reduces high-frequency noise.

C2 : Input coupling capacitor

• DC current suppression.

A reduction in reactance is effective because of increases in capacitor reactance at low frequencies and 1/f noise dependence on signal source resistance which result in output noise worsening.

R2 : Input bias resistor

• Biases the input pin to zero.

• Effects VN stability (refer to NF circuit).

• Due to differential input, input resistance is more or less determined by this resistance value.

R4, R5 : NFB circuit (AC NF circuit). Use of resistor with 1% error is suggested.
