TBA931 Dual NF Amplifier IC - Technical Data and Schematic
Technical data sheet and service documentation for the TBA931 monolithic dual NF amplifier IC manufactured by Intermetall. This detailed reference covers electrical characteristics, complete circuit schematic, die layout information, and NF amplifier design fundamentals with practical guidance for RIAA preamp circuits. Includes frequency response plots, component specifications, and performance data across three noise figure grades: F<6dB, F<3dB, and F<1.5dB. Operating parameters specify 24V supply voltage, 50kΩ input impedance, and 200Ω output impedance. Essential reference for audio equipment repair, vintage audio restoration, and integrated circuit troubleshooting where this dual amplifier stage is used in preamp or low-noise signal conditioning stages.
