This output stage is the brainchild of my friend Kostas, all I did was lay out the PCB. It is a fully discreet single-ended class-A output stage, outputting ~2.4V RMS. And this is the BoM: AK4490 dual mono DAC – Discreet Analog stage BOM (371 downloads) The BoM includes part numbers for most parts from Mouser. […]

Today we’re proud to announce the release of EAGLE 8.7 and what is quite possibly one of the biggest releases we’ve had to-date, this time focused (largely) on libraries and library development (and what that means for 3D modeling of your finished PCB)! But before we get into it, let me share a thought —

Back in 2007, Technologic Systems announced the TS-7800, a single-board computer (SBC) that was able to boot Linux 2.6 in under two seconds. At its core, The TS-7800 is equipped with a Marvel 500MHz ARM9 CPU and includes a user-programmable on-board FPGA (Field-Programmable Gate Array) with 12,000 LUTs (look-up tables). The TS-7800 was a powerful board at that point and a template for other

Modern battery operated portable devices use smart battery packs. Every new development of an electronic medical device must follow strict design flow defined by world-wide or local regulatory directives. The development process of any such device using smart battery pack requires specific operating conditions to meet the testing criteria. When smart battery pack is one

The new STM32WB from STMicroelectronics is a new wireless supporting System on a chip (SoC) that comes with a fully-featured ARM Cortex-M4 (@ 64 MHz) based microcontroller to run the main computing processes. It also has an ARM Cortex-M0+ core (@ 32 MHz) to offload the main processor and offer real-time operation on the Bluetooth
In this post I’m going to show you how you can monitor the power consumption of your battery driven (ESP8266/ ESP32) device. Measuring the power consumption over a full activity/ sleep cycle is the precondition to optimize your code for a longer battery runtime. Only with a reliable tool you can decide which code changes

Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain bandwidth; conversely, decreasing the offset voltage increases the current consumption. Many such interactions between op amp electrical characteristics influence one another. With the increasing need for low power consumption
Adding components from Ambiq Micro and Talent Highland, Fujitsu Electronics Europe has increased its Bluetooth Low Energy portfolio. The additional products offer customers high integration, low power consumption and flexibility, says Fujitsu Electronics Europe (FEE), and it has produced the ClickBeetle reference platform (pictured) to facilitate the integration of Bluetooth Low Energy products into applications.

STORY Why: We built the Pirl Charger because we were unhappy with the quality of existing chargers. Few consumers know they gradually ruin their expensive devices by using poor quality chargers that deliver high noise, high ripple energy. Every consumer device comes with a charger, and those are usually well-built, but they usually have only

The board shown here is a breakout board for MC33035 brushless motor controller. It requires an output buffer IPM module or Mosfets to complete the closed loop brushless motor driver. MC33035 IC is the heart of the project; the project provides 6 PWM pulses as well 6 Inverse pulses outputs. On board Jumpers helps to
