Microsoft XBOX IDE/SATA Adapter – Startprobleme – Fehlercode 09
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...
TPA3251D2 - 2 x 175W stereo 350W Mono class-D amplifier
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...
Microsoft XBOX 1.4 power supply PSU startup problems - 5V 12V too low
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...
Signal / frequency / function generator 0.1Hz-200kHz (sine, square, and triangle)
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...
TPA3132D2 vs. MAX9709 measurements EMI / EMV
Comparative measurements between the TPA3132D2 (2 different boards) and the MAX9709.
TPA3132D2 - delay and emergency shut-down (anti-pop) - also for TPA3116 / TPA3118
Who delay of 10ms (TPA3132D2, TPA3116D2, TPA3118D2) is not sufficient (E.g. when using large time constants/coupling capacitors) and want to do something against the "" PLoP turn off can help with 2 comparators, and few passive components.
SigmaDSP program (Sigma Studio ADAU1701 / 1401A EEPROM standalone self-boat)
Who a developer's Kit for the SigmaDSP series of analog devices his own calls, should consider himself lucky - here does the programming, for example, with the "Starlab", easily and quickly. No one has this and want a SigmaDSP (like the ADAU1701) in the...
DSP-Board SigmaDSP ADAU1701 / 1401A SRC4382 PCM5102A
In cooperation with stromrichter.org (D-amp v. 2) a little DSP Board on the basis of the ADAU1701 (ADAU1401A) is currently being built.
KiCAD Eagle3D POV-Ray
On the way away from Eagle to KiCAD, the question remained open so far, whether the "old" Eagle3D scripts can be used further.
