Description
The STK8250 is an original vintage Sanyo thick-film hybrid integrated circuit (IC) explicitly designed to act as the output stage for heavy-duty Audio Frequency (AF) high-power amplifiers. Built on Sanyo's signature Insulated Metal Substrate Technology (IMST), it offers exceptional thermal conduction and stability without requiring complex, external thermistor-driven temperature compensation networks.
Key Features & Specifications:
- Function: Output Stage of AF Power Amplifier with Built-In Quasi-Class A Bias Circuit
- Minimum Continuous Output Power: 50W (at 8Ω load, VCC = ±38V)
- Maximum Supply Voltage: ±56V
- Distortion Control: Zero switching distortion peculiar to traditional Class B designs
- Package Type: Sanyo Case Outline HYB-10 (SIP package with integrated metal backplate)
- Manufacturer: Sanyo Electric Co., Ltd. (Tokyo Sanyo Semiconductor Division)
Perfect for repair technicians and vintage audio enthusiasts restoring high-fidelity (Hi-Fi) stereo receivers, public address systems, and professional studio monitor amplifiers from the analog era.
