TDA7808 is a single chip quad bridge amplifier in advanced BCD technology integrating: a full D/A converter, digital input for direct connection to I2S (or TDM) and powerful MOSFET output stages. The integrated D/A converter allows the performance to reach an outstanding 115 dB S/N ratio with more than 110 dB of dynamic range.
TDA近似计算出来的激发能存在负值，不用TDA近似算出来的结果 …
2023年2月23日 · 第一激发能如果这么小的话（尤其是如果tda的激发能都这么小），一般说明体系有强相关特征，tddft、tda方法结果不可靠。 另外这个结果有点奇怪，数学上可以证明TDDFT的第n个激发能一定是小于等于TDA的第n个激发能的。

2014年12月8日 · 一般认为tda会略微降低tddft的单重态激发态计算精度，而对三重态激发态的结果却有明显改进，但也有文章发现用了tda后单重态激发能也略有改善（也没准儿只是误差抵消所致）。
The TDA 2020 is a monolithic integrated operational amplifier in a 14-lead quad in-line plastic pa ckage, intended for use as a low frequency class B power amplifier. Typically it provides 20W output power (d = 1%) at ± 18V/4n; the guaranteed output power at …
tda1541 vs. PCM56 - diyAudio
TDA is clearly distorted while PCM is much better and distortion is below noise floor. It simply means that in low level music passages you will hear the difference. Both standard implementation as in the CDP. The difference between the chips is that PCM allows for adjustment and TDA does not. This adjustment makes a big big difference.
The TDA7850A is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt27 package designed for high power car radio.
The TDA7052A/AT are mono BTL output amplifiers with DC volume control. They are designed for use in TV and monitors, but also suitable for battery-fed portable recorders and radios. A MCL protection circuit is built-in.
TDA7492 vs TPA3116 Tests - diyAudio
2014年12月26日 · Tested with original HP 19v 90w adapter for power supply & Dayton RS100 mid range & dual magnet bullet tweeter speakers. The TPA3116D2 makes a popping sound on switch on if the volume is reduced below 10k resistance. To avoid this the board 10k preset has to be set at full volume.
TDAH SIN HIPERACTIVIDAD: el TDAH de predominio inatento (TDA) - Test TDAH
El TDAH sin hiperactividad, también llamado TDAH de predominio inatento o Trastorno por Déficit de Atención (TDA), es un tipo de TDAH en el que los síntomas de inatención son predominantes y la hiperactividad es mínima o no se manifiesta.
The TDA7803A is a single chip quad bridge amplifier in advanced BCD technology integrating: a full D/A converter, digital input for direct connection to I2S (or TDM) and powerful MOSFET output stages. The integrated D/A converter allows the performance to reach an outstanding 115 dB S/N ratio with more than 110 dB of dynamic range.
