Analogue / Linear / Mixed Signal ICs

For GaN-based power adaptors with USB-PD outputs, STMicroelectronics has announced an active clamp fly-back controller with a USB-PD 3.1 interface in a single package, that includes galvanic isolation between primary and secondary sides, crossed by a data link. Called ST-OneMP, on its primary side, it is designed to work with one of the company’s GaN half-bridge-plus-driver combo ICs, communicating through ...

Winner Analog Devices – AD4130-8 The AD4130-8 adds digital features to a low power sigma delta ADC, which is in a smaller size package while keeping precision. The power consumption is improved by an order of magnitude compared to competitive devices, while adding functionality and features helps system designers to make designs recyclable and accelerates time to market. The AD4130-8 ...

Delivering many improved major specs over traditional LM324 op-amps, but with rail-to-rail inputs and outputs, STMicroelectronics has introduced a 6MHz all-rounder op-amp family that will operate from a single 2.7 to 36 V supply as well as from ±1.35 to ±18V dual supplies. TSB511, TSB512, and TSB514 are single, dual and quad op-amps respectively. “This wide voltage range and flexibility ...

Texas Instruments has expanded its space-grade analogue portfolio with devices in radiation-hardened plastic packages. “TI developed a device screening specification called ‘space high-grade in plastic’ [‘SHP’] for radiation-hardened products and introduced ADCs that meet the SHP qualification,” according to the company. “TI also introduced product families to the radiation-tolerant Space EP [‘enhanced plastic’] portfolio.” The SHP specification includes BGA packages ...

Farnell has signed a global distribution agreement with Analog Devices (ADI). The company’s mixed-signal and power management products, including new lines as well as legacy products from Maxim Integrated and Trinamic which was bought by Maxim before it was bought by ADI in July 2020. All products are now in stock and available from fast delivery, confirmed the distributor. The ...

Analog Devices has created a power sender and power receiver chip-set for single-pair Power-over-Ethernet (SPoE) that can deliver 52W to a load – neither IC handles any Ethernet data. “Combined with ADIN1100 and ADIN1110 10BASE-T1L industrial Ethernet solutions, customers can reliably transfer both power and data over one kilometre”, according to the company – for example, for industrial Ethernet-APL, which ...

Diodes has created a servo motor controller, complete with H-bridge mosfets and provision for potentiometer position feedback, for brushed dc motors in automotive manual headlight beam servos and industrial control servos. Called ZXBM5408Q, operation is over -40 to +125°C and 8 to 18V (45V transient survival), and up to 800mA (1.5A peak). It integrates voltage and temperature compensated internal references ...

Texas instruments has introduced a precision bi-directional current sense amplifier than can measure voltage drops across shunt resistors over a common-mode range of -5 to 110V, with survival across -20 to +120V. Bias current is 35µA within the operating range, and that operating range is independent of the 2.7 to 20V single rail supply voltage, from which 2.5mA is drawn. ...

NXP announced a pair of eight input analogue front-end ICs for factory automation at Electronica this morning. Both have inputs that can measure ±25V, with the NAFE71388 being nominally ‘high speed’ and the NAFE11388 ‘low power’. They both have the same block diagram, and connect to a host over a 32MHz SPI bus. CRC error detection is included, and there ...

Infineon has introduced an automotive current sensor IC, available in four pre-programmed current ranges: 25, 50, 75 or 120A. Called TLE4971, they are “ideal for on-board chargers, high-voltage auxiliary drives and charging applications”, according to the company. “Additionally, the sensor is also ideal for industrial applications including dc chargers for electric vehicles, industrial drives, servo drives and photovoltaic inverters.” Inside, ...
