On the basis of experience and measurements with TPA3251 boards from TPA3251D2 - 2 x 175W stereo 350W Mono class-D amplifier rises the "TPA3245/51/55 - universal" Board for up to 600W (PBTL Mono).
Based on the "shrink"mod Board this TPA3251 amplifier variant in an aluminium casing, which also serves the heat dissipation was created.
Many inexpensive electronic circuits from the far East (mainly China) containing capacitors with unknown or little or no appropriate operating parameters, dubious origin or partly subject to fake / fakes / imitations of well-known brands. Here is a list.
As an extension of the "Akita" family Texas instruments has, due to the TPA3251D2 a "big brother" available - the TPA3255 (HTSSOP44). By adjusting the input voltage range on maximum 53.5V for example, a direct is operating at 10 s Pedelec battery possible. PIN compatibility allows a direct...
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).
When using an Agfa Snapscan e52 (also, e10, e20, e25, e26, e40, e42, e50, 1212u, 1236u) with the software Scanwise 2.0.0.x connected via USB (here 126.96.36.199) on newer operating systems (Windows XP, Vista, 7) it comes sometimes to communication problems between the...
