Tilt measurement using a single axis accelerometer

A single axis accelerometer is a device that measures acceleration in one direction. It is typically used to measure acceleration along a single axis, such as up and down or left and right. Output of…

Photodiode biasing (Photoconductive or Photovoltaic mode)

A photodiode is a type of semiconductor device that converts light into an electrical current. It can be used with or without a reverse bias applied. Reverse biasing a photodiode is accomplished by…

SPI Daisy Chain Example for L6470

The L6470 is a fully integrated motor driver. It provides a complete standalone solution for stepper motor applications. The L6470 is controlled by a host microcontroller (MCU) through a fast 8-bit…

High voltage current sensing circuit

High-side current sensing is used in a wide range of applications. Usually, it is used for overcurrent protection in power management circuits. On the market, there are many off-the-shelf operational…

Low-side buck (step-down) converter

A buck converter is a simple type of DC-to-DC converter that produces an output voltage that is less than its input voltage. In other words, this DC-to-DC converter steps down the voltage from its…

High-speed photodiode circuit

The high-speed photodiode circuit in Figure 1 uses a low capacitance PIN photodiode (PD), load resistance (RL), and a high-speed operational amplifier (U). In this configuration, the photodiode is…
