Analogue / Linear / Mixed Signal ICs

STMicroelectronics has added a 30MHz 50µV input offset dual device to its 5V op amp family. Called TSV782 and working down to 2V, allowing it to use the same power rail as low-voltage logic devices, and consumption is 3.3mA/channel – there is no shut-down pin to reduce this. Slew rate is 20V/µs, and TSV782 has maximum input bias is 300pA up ...

Diodes has used post-package trimming to hone a 25μV maximum offset 9.5nV√Hz (1kHz) noise dual op amp with 5.5MHz bandwidth. Called AS2376Q, the device is intended for filtering and control, particularly in automotive applications – it is qualified AEC-Q100 Grade 1 and has automotive-grade supporting PPAPs. Both input and output are rail-to-rail, and operation is over 2.2 to 5.5V (950μA ...

STMicroelectronics has used the ‘CAN FD Light’ protocol in a 32-channel automotive lighting controller. “With 32 regulated current sources, independently programmable from 1mA to 15mA, L99LDLH32 can drive individual pixels in external and interior lighting applications. Global dimming is also provided, with 8-bit resolution,” according to the company, whose data sheet said that it is particularly aimed at external rear ...

Alps Alpine is aiming at safety redundancy, particularly in vehicle power steering, with a pair of magnetic angle sensors on two separate die inside the same package, positioned to share the same external magnet. “Redundancy design is increasingly a requirement for automobile driving systems,” according to the company. “The use of multiple sensors was once the typical way of realising ...

Toshiba has introduced a smart gate drive photo-coupler with automatic recovery from some fault conditions. Capable of driving ±2.5A into an IGBT or mosfet gate, it is called TLP5222, and is a partner to the TLP5212 announced earlier this month, which needs a signal on the primary side to initiate recovery from fault conditions. “TLP5222 continuously monitors the mosfet drain-source ...

Rohm is aiming at automotive and industrial equipment requiring functional safety with a 40V window voltage detector and reset IC. Called BD48HW0G-C, it is a CMOS IC made on the company’s high-voltage BiCDMOS process. The supply pin is allowed up to 42V abs max, as are the two (40mA abs max) open-drain output pins. The inputs can handle a maximum ...

Diodes has announced a 600mA automotive-compliant dc-dc converter that can run from 4.5 to 40V. Called AP64060Q, the parts include a 600mΩ high-side and a 300mΩ low-side mosfet – the latter making an external Schottky optional. Quiescent current is typically 90μA, according to the company. Two resistors are needed to set output voltage, and anywhere up from 0.8V – with ...

Diodes has announced precision bi-directional current monitors in a 2.2 x 2.2mm package. Called the ZXCT199 series, they are rail-to-rail voltage output type devices with gains of 50V/V, 100V/V or 200V/V. Input is taken across a shunt resistor at common-mode voltages from -0.1V to +26V (typically 120dB common-mode rejection), independent of the 2.7 to 26V supply voltage, from which a ...

Cambridge-based Agile Analog has announced RC oscillator intellectual property for IC designers. Called ‘agileOSC RC’, it “is based on a traditional architecture which allows the frequency to be trimmed to remove the effects of process variation,” according to the company. It can also be configured as a free running clock where a high accuracy clock is not required. Start-up is typically ...

Agile Analog has added a voltage sensor to its portfolio of intellectual property, for IC designers that need to monitor fluctuations on on-chip power rails. Called ‘agileIR Drop’, despite its name, it does not monitor the voltage difference from end-to-end of a conductor. Instead the IP block provides real time monitoring of voltages at single points on rails to detect ...
