Analogue / Linear / Mixed Signal ICs

Analog Devices has released some details of a 10GHz bandwidth analogue front-end, possibly to be revealed in full at IMS in San Diego this week. The 16nm CMOS device is said to have four 12bit 20Gsample/s ADCs and four 16bit 28Gsample/s DACs – and seems like a faster cousin of the 28nm AD9081 released a few years ago – if ...

The OPAx992-Q1 family of 40V rail-to-rail op-amps from Texas Instruments are AEC-Q100 qualified for automotive use. There are single (OPA992-Q1), dual (OPA2992-Q1) and quad (OPA4992-Q1) versions. Intended to be general purpose, the amplifiers’ differential and common-mode input ranges reach the supply rails. 115dB common-mode rejection is claimed, and the devices are rated to be used as comparators as well as ...

Microchip has created a set of dual-channel single-lane USB 3.2 Gen1 SuperSpeed reclocker redriver ICs for automotive and industrial cables up to 15m long. “Adding electronic components to applications across automotive, industrial and consumer industries has spurred the need for far-reaching USB cabling products,” according to the company. EQCO510 is the automotive version, qualified to AEC-Q100 Grade 2 and operates ...

Toshiba is aiming at over-temperature detection in mobile devices and home appliances with a family of ICs, intended to work with positive coefficient thermistors. Power consumption is under 12μA with 10μA of that going through the thermistor as sensing current. Lower current (<2μA) versions are planned. Inside is a current source to feed the PTC and a reference voltage with ...

Texas Instruments has releases an RS-485 transceiver that can be pin-programmed to suit networks with different bus voltage, logic voltage, network length and throughput. Called THVD1424, it includes switchable on-chip 120Ω termination resistor, slew rate control, and both half-duplex (two-wire) and duplex (four-wire) modes – allowing a single PCB type to be created that can be software re-configured for different ...

Infineon has introduced automotive high-side power switches for safety-critical circuits. ‘Load Guard 12V’ dual and single-channel are available with nominal current carrying of 2 or 3A, making four devices in total. Without the host MCU getting involved, a pad is provided (OCT in diagram right) for an RC network that can modify the level and timing of current limitation above ...

Rohm has developed four and six channel automotive LED drivers for 5 – 10in+ backlights behind displays and instrument clusters. The parts (table below) include 20,000:1 PWM dimming and dc dimming in a way which “eliminates flickering when changing display brightness from low to high”, according to the company. Switching can be between 200kHz and 2.4MHz, and operation is over ...

At APEC in Florida, Texas Instruments introduced a family of ICs designed to shrink the size of EMC anti-emission common-mode filters in single and three-phase mains and automotive power converters. In principal, the ICs implement a capacitance multiplier circuit to emulate the Y-capacitors in a conventional passive filter design. They do while sitting amongst smaller filter inductors and capacitors (top ...

For Li-ion battery packs up to 25V, STMicroelectronics has introduced an IC for monitoring, balancing and protection, aiming at cordless power tools, back-up energy storage and medical devices. Called L9961, its “built-in features include a dual pre-driver for controlling battery-pack safety relays, which can be programmed for high-side and low-side connection”, said ST. “An embedded non-volatile memory for configuration data ...

Diodes has introduced AP7387Q, an LDO linear voltage regulator with a 5V to 60V input range and typically 700mV at a 100mA output current. “Thanks to its wide input voltage, the AP7387Q meets the load dump specifications of 12V internal combustion engine vehicles such as cars and 24V combustion engine vehicles such as buses, coaches, and trucks”, the company said. ...
