Analogue / Linear / Mixed Signal ICs

TDK has announced automotive smart motor drivers that can handle 4 x 1A peak current and include an Arm Cortex-M3 processor core. HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ...

Abaco Systems latest analogue front-end mezzanine card for FPGAs has been tailored for software defined radio, as well as electronic warfare, radar, test and measurement. FMC300, as it will be known, has 7GHz of usable analogue bandwidth, claims the company, with multiple channels offering up to 12bit 6Gsample/s ADC and up to 16bit 12Gsample/s DAC through a JESD204B/C interface. Data ...

Analog semiconductor manufacturer ABLIC Inc. embarked on a new start under a new company name in 2018, against the backdrop of a rich history spanning over 50 years. In June 2023, five years later, Seiji Tanaka took office as the new president. While focusing on planning and development capabilities as well as high-value-added products, Tanaka is also strengthening initiatives in ...

Nexperia has unveiled analogue switches that can work with control logic from 1.8 to 5V, regardless of supplies between 1.5 and 5.5V. There are two versions: NMUX1308, an 8:1 analogue multiplexer/demultiplexer which is compatible with, but more capable than, existing 4851 and 4051 analogue switches, and the NMUX1309 dual 4:1 analogue mux/demux which can replace 4852 and 4052 devices. All ...

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers instead of CAN, or a CAN interface without transceivers, or no CAN or LIN, and a base model has a 70MHz processor. Some have SENT interfaces for ...

Rohm is aiming at industrial and consumer applications with a ‘zero-drift’ operational amplifier which scores 9µV and 50nV/°C for its input offset – both maximum figures, which are typically 1µV and 15nV/°C. A first for the company, LMR1002F-LB, as it will be called, has a chopper architecture. Input current is typically 150pA (25°C) with 10pA offset. Both inputs and output are ...

Novosense Microelectronics has created a pair of isolated digital input chips suitable for 24V industrial control applications that only need power on the output side. 4-channel NSI8604 (SSOP16 package) and 8-channel NSI8608 (SSOP20) provide input/output isolation when converting voltages in the range of -60V to 60V to logic signals. (The third digit is a capital ‘i’, not a numerical ‘1’). ...

This chipset provides new levels of connectivity with the world’s first commercially available devices using 3GPP NTN technology. It allows the use of satellite networks for reliable communication in remote locations, bringing connectivity to previously inaccessible areas, for use in agriculture, forestry and logistics. Judges were impressed with the evidence of its impact with one describing it as an “impressive ...

Microchip has announced 10 automotive-grade multi-channel temperature monitoring ICs that use external diodes, transistors or substrate diodes (MCU or other die) as sensors. Called the MCP998x family, they communicate over a serial bus and a pair of discrete output pins. Accuracy is ±1°C max (±0.2°C typ) with the IC and probe diodes anywhere in the range +20°C to +85°C – ...

Allegro MicroSystems has created an isolated gate driver IC for GaN power transistors that has no need for high-side bootstrapping nor the provision of a secondary side drive supply voltage. Instead, a dc-dc converter within AHV85111 produces secondary-side dc power rails – one positive and one negative – to provide gate drive power from a 12V supply (10.8 – 13.2V) ...
