Product Summary

The STK4050V is an AF power amplifier. Supports addition of the STK4050V 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.

Parametrics

STK4050V absolute maximum ratings: (1) Maximum supply voltage VCC max: ±95V; (2) Thermal resistance θj-c: 0.95°C/W; (3) Junction temperature Tj: 150°C; (4) Operating substrate temperature Tc: 125°C; (5) Storage temperature Tstg: -30 to +125°C.

Features

STK4050V features: (1) Compact packaging supports slimmer set designs; (2) Series designed from 20 up to 100 W (200 W) and pin-ompatibility (120 to 200 W have 18 pins); (3) Simpler heat sink design facilitates thermal design of slim stereo sets;(4) Current mirror circuit application reduce distortion to 0.08 %; (5) 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.
