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...
Comparative measurements between the TPA3132D2 (2 different boards) and the MAX9709.
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.
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...
In cooperation with stromrichter.org (D-amp v. 2) a little DSP Board on the basis of the ADAU1701 (ADAU1401A) is currently being built.
Stroboscope in your Pocket? Bring it! The following "product", the "Dizzler" was resurrected with minimal use of materials.
On the basis of the TPA3132D2 of Texas instruments, a small 50 50W is amplifier in the pipeline. Update (09.01.2015): Revision 0 d in operating update (06.02.2015): switch-on delay and emergency shut-down option Update (04.08.2015): added pictures of the final version at the end of the contribution (Rev...
