Package

TDA7266SA Manufacturer

STMicroelectronics, headquartered in Plan-les-Ouates, Switzerland, near Geneva, is a multinational electronics and semiconductors firm. The company was created in 1987 by the merger of two government-owned semiconductor companies: "Thomson Semiconductors" in France and "SGS Microelettronica" in Italy. It is known as "ST" and is the most profitable semiconductor chip producer in Europe. While the corporate headquarters and EMEA regional offices of STMicroelectronics are in Geneva, the holding company, STMicroelectronics N.V., is based in the Netherlands.

Frequently Asked Questions

1.What is the working voltage of each pin of the color TV power amplifier TDA7266SA?
TDA7266SA each pin function and voltage: • Pin 1: The positive output of the left channel, 6.37 volts. • 2 feet: Left channel negative output, 6.4 volts. • 3 feet 13 feet are the power supply, 16 volts. • 4 feet: right channel input, 1.52 volts. • Feet 5, 10, and 11 are empty. • 6-pin mute, 4.2 volts (voltage during normal operation, 0 volts when mute). • 7-pin standby, 4.43 volts. • 8 and 9 feet are ground. • 12-pin left channel input, 1.52 volts. • 14-pin right channel positive output, 6.35 volts. • 15-pin right channel negative output, 6.35 volts.
2.Can TDA7266SA power amplifier block be replaced with 7266MSA?
If the working voltage is about 12V, it should be replaced, but if the supply voltage is 18V, it is best not to replace it. TDA7266SA has different tail numbers and different operating voltages, but the typical value is 11V. It is safer at this voltage, but the sound is lower than 18V. It can also be replaced with TDA7297. This is a dual 15W, which is louder than the original sound. If the power supply circuit can withstand it, this chip is better. The premise is that it can be bought.
3.Can TDA7266SA replace TDA7253?
The direct replacement is definitely impossible because the two chips are very different in function, pin, package and even working voltage; especially TDA7266SA is a bi-amp, and TDA7253 is a single-amp.
4. What is a dual bridge amplifier built specifically for LCD monitors?
TDA7266SA.
