TPA3255 / TPA3251 / TPA3245 Rev.1B Final
In continuation / expansion of implementations based on the TPA3255 / TPA3251 / TPA3245 here's the final recognition of an amplifier designs for Akita family. Unlike before, the analog front end is integrated on a dedicated circuit board and symmetrically provided. This results in ...
TK15 Battery Tester Coulometer 80V 15A 1mR Isabellenhütte from Baiway,,de,31 May, 2018,,en,2018 (1),,en
Baiway hat mit dem TK15 einen 80V 50A Ladungszähler/Batterietester mit abgesetztem Shunt im Angebot. Vorliegend hier die Version 6.
TPA3128D2 – 2 x 30/50W Stereo 60/100W Mono Class-D Verstärker
Mit dem TPA3128D2 bringt Texas Instruments einen Nachfolger des TPA3118D2 heraus, welcher die Vorteile von 1SPW und BD Modulation in einem Hybrid-Modus kombiniert. Gleichwohl wurde die Ausgangsstufe überarbeitet (Rds_on = 90mR vs. 120mR) sowie die minimal zulässige Betriebsspannung gesenkt. Bereits...
TPA3221 – 2 x 100W Stereo 200W Mono Class-D Amplifier
With the Texas Instruments TPA3221 brings a descendant of Akita Family out (TPA3251 TPA3255) which integrates prepress and analog voltage generation. It is thus be appropriate to replace the previous "long-running" TPA3118 TPA3116 as well. Other future members of this family (Boxster) are TPA3220, TPA3223 ...,de
Comparison of power Bank for IoT ESP8266, ESP32, Arduino, GPS, Bluetooth
Power banks are a convenient means of choice for supplying small projects such as IoT, streaming or sensors. But what's with low quiescent current, efficiency and maximum performance? Ideally the cells should be Exchange or compile initial. Pre tipped (cheap) power banks...
Universal AFE – Analog Front End – TPA32XX TPA3245 TPA3251 TPA3255 mit PFFB
In preparation of the "final" version of the TPA32XX amplifier ((TPA3245, TPA3251, TPA3255) there's a dedicated AFE module 2-stage design with mail filter-feedback (PFFB).) The implementation of PFFB relating to this module also works for other class D ICs, such as, for example, TPA3116, TPA3118...
