AKM releases a 3-axis Magnetic Sensor for IoT Designs; The AK09970 captures Magnetic Fields with Vector Components
22.02.2017 · News
There is increasing demand for a sensing function to monitor an object’s status in remote locations as IoT products are expected to grow in the market. Asahi Kasei Microdevices Corporation, (AKM), has developed the AK09970, a 3-axis magnetic sensor that is able to detect magnetic signals in X, Y, and, Z directions. The AK09970 supports wide measurement range with high resolution in 3-axis detection and captures magnetic fields in 3-dimensions...
560V No-Opto Flyback Regulator Delivers Up to 15 Watts in High Voltage Spacing TSSOP Package
22.02.2017 · News
Linear Technology Corporation announces the LT8315, a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation...
Optical sensor needs no tweaking
21.02.2017 · Circuits
The transfer gain of optical sensors spans a 16-to-1 ratio because of variations in the LED, phototransistor, ambient temperature, and optical path. The wide transfer-gain variation complicates output-resistor selection in dc-coupled circuits. You must size the output resistor to prevent high transfer gains from causing output-stage saturation, but low transfer gains yield low output-voltage swings with low-value resistors...
When to use an amplifier with rail-to-rail inputs - and what to watch out for
21.02.2017 · Articles
Early in my graduate school education, I was working on a project that needed a unity-gain operational-amplifier buffer for a monitoring circuit in our thin film deposition system. As soon as the new module was plugged in, I discovered that all of the signals close to the positive supply were clipped...

Circuit Enhancement Enables Digital Setting of Voltage Reference
19.02.2017 · Articles
Adjustable voltage references offer great flexibility to circuit designers because the reference isn’t limited to the manufacturer’s preset values. The adjustable output is typically configured with a voltage divider from the output to the feedback pin. To regulate the output, the circuit compares the voltage at the feedback pin to an internal reference...
