Microchip announces its latest 2.4GHz RF high-power amplifier, the SST12CP12, which adds support for the 256-QAM ultra-high data rate modulation. With its high linear output power of up to 23dBm at a dynamic EVM as low as 1.8% and MCS8 40MHz bandwidth modulation, as well as 25dBm linear power at 3% EVM, this amplifier significantly […]

Murata announced the DMR20-1-ACV “nanometer” self-powered four-digit bright LED voltmeter. This line powered AC voltmeter can measure the true RMS value of its input from 85 to 264 VAC to within 0.1 V resolution. Designed to be completely self-contained, the low cost two-wire voltmeter requires no additional components or connections apart from the AC voltage […]

Microchip announces the expansion of its programmable USB port power controller portfolio with the three-member UCS100X family. These new power controllers offer advanced USB-based charging capabilities for designing host devices, such as laptops, tablets, monitors, docking stations and printers; as well as dedicated AC-DC power-supply and charging products, such as wall adapters. Microchip’s new USB […]

Murata announced the compact DMR20-10-DCM “nanoMeter” self-powered auto-ranging DC voltmeter designed for mounting in an industry-standard “oiltight” 30 and 30.5 mm / 1.2 inch round panel cutout. Occupying minimal space, the round voltmeter has a 7.6mm / 0.3 inch four-digit LED display and is self-powered. Connection to the + 6 to + 75VDC supply to […]

Maxim Integrated Products, Inc. announced that it is now sampling the MAX31850/ MAX31851 cold-junction-compensated, 1-Wire® thermocouple-to-digital converters. The devices achieve ±2.0°C accuracy (not including sensor nonlinearity) while integrating all of the functions required for a complete thermocouple-to-digital solution. Additionally, the MAX31850/MAX31851’s 1-Wire interface allows multiple sensor locations to communicate and draw power over a single […]

Microchip announces a new nine-member low-power, general-purpose operational amplifier (op amp) family – the MCP647X/8X/9X. These op amps provide among the industry’s best power consumption for a given gain-bandwidth product, including low quiescent current, to extend battery lifetimes. Additionally, they have exceptionally low leakage current over temperature, up to 125°C, which reduces errors in applications […]

Microchip announces two new volatile, SPI digital potentiometers (digipots), the MCP41HV31 and MCP41HV51 (MCP41HVXX), which are its first to operate at 10, 12, 18, 24 and particularly 36 volts, for systems requiring wide signal swing or high power-supply voltages. Additionally, these digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including […]

Silicon Labs introduced the industry’s first digital CMOS-based drop-in replacement solution for optocoupler-isolated gate drivers (opto-drivers). Supporting up to 5 kV isolation ratings and up to 10 kV surge protection, the new Si826x isolated gate drivers provide an ideal configuration, package and footprint fit for a wide range of opto-drivers used in high-power motor control, […]

Maxim Integrated Products, Inc. announced it is sampling the MAX14920/MAX14921, high-accuracy, 12/16-channel cell-measurement analog front-ends (AFEs) that lower battery-management electronics costs by up to 35%. These devices double the accuracy of cell voltage readings through the use of high-accuracy common-mode level shifting and an integrated high-precision amplifier that simplifies ADC data conversion. Higher accuracy improves […]

Microchip announces the MCP19111, the world’s first digitally enhanced power analogue controller, which expands Microchip’s diverse range of intelligent DC/DC power-conversion solutions. Microchip also announces the expansion of its high-speed MOSFET family, with the new MCP87018, MCP87030, MCP87090 and MCP87130. Rated at 25V, these 1.8mΩ, 3mΩ, 9mΩ and 13mΩ logic-level MOSFETs are optimised for Switched-Mode-Power-Supply […]
