TBA790 Description

Short technical summary and product information.

The Bourns TBA790 is an integrated circuit (IC) functioning as a power AF amplifier, also known as an NF-Endstufe. It is constructed internally with 22 transistors, 10 resistors, and 1 capacitor.

 

Key electrical specifications include a maximum supply voltage (Vcc) of 12V, with variants supporting up to 15V or 18V. The output power (P out) ranges from 0.65W to 3.45W, with a typical quiescent current (Iccq) between 6mA and 10mA. The input resistance (R I) is 50 MΩ, and the maximum junction operating temperature (tmax j) is 125°C.

 

This component is available in two package outlines: QIP-14 and RP14. The dimensions of the package including pins are 18 x 7 x 8 mm, with a weight of 1g. It is similar to the ESM231N from COSEM.

 

This IC is suitable for applications requiring audio frequency power amplification, commonly found in vintage audio equipment.
