TA8254BHQ Description

Short technical summary and product information.

The TA8254BHQ from Toshiba is a silicon monolithic bipolar linear integrated circuit designed as a BTL stereo audio power amplifier. It is particularly suited for car audio systems and is optimized for 2-ohm load impedance.

Key electrical specifications include a high power output of up to 45 W (typ.) per channel at 14.4 V supply and 2-ohm load. It also features a low distortion ratio of 0.02% (typ.) and low noise of 0.10 mVrms (typ.). The operating supply voltage range is from 9 V to 18 V, with a typical supply current of 250 mA.

This audio power IC incorporates several functional and protection features. These include a stand-by function, a muting function, a diagnosis circuit with an output clipping detector, and various protection circuits such as thermal shutdown, over voltage protection, and short circuit protection (OUT to VCC, OUT to GND, and OUT-OUT). The device has a total voltage gain of 26 dB.

The TA8254BHQ is housed in an HSIP package suitable for through-hole mounting. Its operating temperature range is from -40°C to 85°C. The weight is approximately 4.0 g.
