IBM scientists achieve storage memory breakthrough

The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry’s attention as a potential universal memory technology based on its combination of read/write speed, endurance, non-volatility and density. For example, PCM doesn’t lose data when powered off, unlike DRAM,

ST has MEMS gyro for more than

The L3G4IS is the first three-axis MEMS gyroscope that enables both user interface and image stabilization applications at the same time. Thanks to two different independent reading chains and digital interfaces, the L3G4IS delivers previously unseen levels of flexibility to the end user. Each reading chain and the corresponding full-scale can be activated by powering

ODrive – High performance motor control

Description Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to other kinds of projects like air hockey robots, use them. However in industrial automation, brushless servomotors have taken

Range of I2C-bus NXP extends with no-offset buffer

The PCA9525 is a monolithic CMOS integrated circuit for bus buffering in applications including I²C-bus, SMBus, DDC, PMBus, and other systems based on similar principles. The buffer extends the bus load limit by buffering both the SCL and SDA lines, allowing the maximum permissible bus capacitance on both sides of the buffer. The PCA9525 includes

TI claims zero-drift op amp first

Description The OPA2188 operational amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25 µV, max), and near zero-drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes the negative rail. Either
