STK4042V Overview
Input filter circuit R1, C1 Reduces high-frequency noise. 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.
STK4042V Key Features
- pact packaging supports slimmer set designs
- Series designed from 20 up to 100 W (200 W) and pinpatibility (120 to 200 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 mut
- 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 frequen
- 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 (A
