25W 25W STEREO CLASS-D AMPLIFIER 50W MONO IN BTL
The TDA7490 is a 25-pin ZIP (ZIP-25) power amplifier IC manufactured by STMicroelectronics. It is a monolithic integrated circuit designed for use in stereo and bridge-tied load (BTL) audio amplifier applications. Description: The TDA7490 is a high-performance, low-power, stereo audio amplifier IC that can deliver up to 25 watts of output power per channel into a 4-ohm load. It features a wide supply voltage range of 4.5V to 18V and a low quiescent current of only 4mA. The TDA7490 also features a low distortion level of 0.02% and a high signal-to-noise ratio of 90dB. Features: High output power: 25W per channel into 4Ω Low quiescent current: 4mA Wide supply voltage range: 4.5V to 18V Low distortion: 0.02% High signal-to-noise ratio: 90dB Thermal shutdown protection Short-circuit protection Over-voltage protection Applications: The TDA7490 is suitable for use in stereo and bridge-tied load (BTL) audio amplifier applications, such as portable audio systems, car audio systems, and home audio systems. It can also be used in other applications that require high-performance, low-power audio amplification. (For reference only)
