ORP / Redox / PH electrometer Shield for Wemos D1 Mini with LMP7721 ADS1115 ADM3260
Presented is a shield, compatible with the Mini Wemos D1, alternatively generically I2C any on each controller. Implemented is an electrometer amplifier for measuring pH / redox / ORP potential based on the TI LMP7721.
Universal System Voltage Supervisor (SVS) - Voltage Monitors
To batteries and systems et al to protect mobile systems against voltage is too low, the use of a "System Voltage Supervisors" (short or SVS voltage monitor) offers. Based on the MIC8114 this little circuit is created which some useful additions to ...
LM5069 – Hot Swap Controller / Load Switch / Battery Switch
Load Switch / battery switch based on the LM5069 for 10-50V input voltage and 120A +. To use the 1200W Boost converter in combination with the TPA3255 amplifier sealed lead / SLA, Li-Ion or other sources, an electronic switch is necessary, the above-mentioned performance parameters with up ...
LTC3784 – 1200W Polyphase Boost Converter
Mit einem Eingangsspannungsbereich von 10-50V stehen ausgangsseitig 1200W bei 50V zur Verfügung wobei die maximal mögliche Dauerleistung von der Eingangsspannung sowie thermischen Anbindung limitiert wird. Der Wirkungsgrad bei 11V Eingangsspannung und 750W Ausgangslast ist besser 95%. Bei Abruf von 1200W...

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 ...
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...
