In analogy to the TABE family (TAS5630B, TAS5613A, TAS5611A) Texas instruments has, due to the TPA3251D2 a "little brother" with unterseitigem Thermalpad available - the TPA3250D2 (HTSSOP44).

By timing problems when using an IDE/SATA Adapter it can happen that the XBOX quitiert a startup with the error code 09. Workaround here can establish a connection between Pin1 of the IDE interface on the IDE/SATA Adapter (/ reset) and R3G3 on the motherboard (3.3V...
In analogy to the TAS family (TAS5630B, TAS5613A, TAS5611A), Texas instruments introduced a new class-d chip amplifier, the TPA3251D2 (HTSSOP44). Specs are: differential analog inputs 2Vrms 90% efficiency (4 ohm) 12-36V power supply 2 x 175W at 4 Ohms BTL (10% THD) 2 x 220W...
At low voltage level on the 5V and 12V rail is there to system instability and startup problems. First and foremost, this is expressed in sporadic interruptions of the hard drive and the DVD drive. As both voltages are monitored together, the voltage dip is percentage...
A simple (fully analog) frequency generator can be finished using a 4 x op-amp (LMH6644), 6 transistors and a few passive components. The symmetrical power supply ( /-5-12V) using either a transformer or a charge pump. (The circuit can be a discreet substitute for MAX038...
