Difference amplifier measures high voltages
30.03.2017 · Circuits
Figure shows two large-signal- measurement methods. The first uses a two-resistor voltage divider and an output buffer, and the second comprises an attenuating inverter and a high-value input resistor. Both of these approaches introduce measurement-linearity errors because only a single resistor dissipates power...
Ultra-Low-Current LDO from Diodes Incorporated Handles Loads up to 150mA with 1% Accuracy

Diodes Incorporated introduced the AP7350. This low dropout voltage regulator (LDO) is available with output voltages from 1.2 V to 3.3 V, supporting load currents up to 150 mA. The AP7350 targets low-power, handheld and wearable device applications...
Intel takes another step into the Arduino world
The Arduino began life as a simple and inexpensive 8-bit microcontroller teaching tool. In the intervening decade plus, it’s grown into a diverse platform that has revolutionized the microcontroller education and hobby worlds. Recent, more powerful additions to the Arduino family have added 16 and 32 bit processors and have brought the Arduino into commercial development as a rapid prototyping platform...

29.03.2017 · News
CML Microcircuits is pleased to announce the release of a new range of RF Building Blocks: RF Power Amplifiers. The CMX901 is the first product in its range to be released and is a three-stage wideband, high gain and high efficiency RF power amplifier IC operating over 130 MHz to 950 MHz...
Non-Inverting Level Shifter Requires Only One Op Amp, One Supply Voltage
29.03.2017 · Circuits
With portable battery-operated devices continuing to add functionality while shrinking in size, printed-circuit-board real estate becomes increasingly valuable. Single-supply circuitry can help by saving space and cost. Adding audio or video, however, may pose a problem because those signals are usually referenced to ground, and most single-supply ICs must be configured for signals above ground...
Industry's first multiphase bidirectional current controller from TI
29.03.2017 · News
Texas Instruments introduced the industry's first fully integrated multiphase bidirectional DC/DC current controller, which efficiently transfers electric power greater than 500 W per phase between dual 48-V and 12-V automotive battery systems. The highly integrated LM5170-Q1 analog controller features an innovative average current-mode control method that overcomes the challenges of today's high-component-count, full digital control schemes...
Simple Circuit Drives, Manages Laser Diode's Output
27.03.2017 · Circuits
By using a constant-current source along with a ratiometric DAC configuration, the output intensity of a laser diode can be carefully set and controlled using this simple circuit. This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint...
