The TDA7297SA is a dual bridge amplifier specially designed for TV and Portable Radio applications.
The TDA7297SA is a 10W+10W dual bridge amplifier designed specifically for TV and portable radio applications. It features a wide supply voltage range of 6V to 18V, internally fixed gain, and includes built-in stand-by and mute functions along with short circuit and thermal overload protection.
| Supply Voltage Range | 6.5 to 18 V |
|---|---|
| Output Power (THD 10%) | 8.3 W typical, 10 W max |
| Total Harmonic Distortion (Po = 1W) | 0.1 to 0.3 % |
| Total Quiescent Current | 50 mA typical, 65 mA max |
| Operating Temperature Range | 0 to 70 °C |
The device operates with a supply voltage ranging from 6.5V to 18V.
No, it is designed to operate without an SWR capacitor, no bootstrap circuit, and no Boucherot cells.
A delay of 100-200ms between the Stand-By and mute signals is suitable for proper operation to avoid pop noise.
