Analogue / Linear / Mixed Signal ICs

NXP has announced a suite of 77GHz tranceivers and radar processors “that address NCAP requirements for corner and front radar applications while offering ‘4D’ imaging radar’s first commercially viable path to volume production, according to the company. ‘4D imaging’ radar adds direction, angle of arrival and elevation measurement to simply measuring range and speed. The parts are the S32R294 processor, the S32R45 processor and TEF82xx ...

L7983 is a 3 to 60V input 300mA output synchronous dc-dc converter from ST Microelectronics whose mode can be pin-selected to keep noise down or maximise efficiency at light load The variable output variant can provide from 850mV to Vin. Low noise operation mode is essentially fixed frequency, and low consumption operation is variable frequency with single output pulses or bursts ...

Diodes is aiming at image sensors and cameras in smartphones and other mobiles with a MIPI 2:1 switch for D-PHY and C-PHY signals. Called PI3WVR628, it is a six channel single-pole, double-throw (SPDT) switch supporting two data lanes plus a clock lane for D-PHY signals, or two lanes for C-PHY signals. Optimisation is for rapid switching between high-speed (HS) and low-power (LP) ...

At Electronica, Grenoble-based Teledyne e2v revealed a 12bit 11Gsample/s ADC proof-of-concept “able to deliver performance parameters that are beyond the scope of anything currently on the market”, it claimed, “It can achieve SHF [super-high frequency] direct sampling, reaching all the way into the Ka frequency band. Called EV12PS640, it was demonstrated alongside the recently announced EV12DD700 12bit 12GSample/s (26GHz bandwidth) dual channel DAC. ...

Teledyne e2v is offering beta samples of its 12Gsample/s 12bit (or 8bit) EV12DD700 dual-channel DAC. “What sets it apart from other DACs is that it is first on the market to support operation within the 26GHz upwards Ka-band,” claimed the company. “Numerous features have been incorporated, such as DDS [direct digital synthesis], plus digital up-conversion via a built-in 32bit NCO ...

Maxim has announced a suite of integrated circuits and reference designs for industrial automation using IO-Link communications. IO-Link is a short-range (<20m) point-to-point industrial bus developed to connect sensors and actuators to a local hub, from which the data is transferred to a remote PLC (programmable logic controller) via Ethernet or other long-range field bus. “The IO-Link interface allows every ...

Maxim is measuring blood oxygen, ECG, heart rate, body temperature and activity data in its third generation of wearable health monitor reference design, this time entirely wrist-worn. Called Health Sensor Platform 3.0 (aka MAXREFDES104#), it comes in a ready-to-wear wrist form with algorithms to provide heart rate, heart-rate variability (HRV), respiration rate (RR), SpO2 , body temperature, sleep quality and ...

Toshiba has released an micro-power CMOS operational amplifier, drawing a maximum of 600nA and typically 270nA (1.5V supply, -40 to 105°C). Called TC75S102F, it will run from supplies between 1.5V and 5.5V and is rail-to-rail on both input and output. Unusually for an op-amp, no input excursion outside the rails is allowed at all. “Operational amplifiers have a multitude of uses including ...

Microchip has announced low-power DACs that self-configure at power-up, using internal non-volatile memory instead of host processor intervention. They are DACs with multiple channels, built-in EEPROM, a built-in reference and an I2C interface: MCP47FEBx4 quad channel MCP47FEBx8 octo channel MCP48 parts have similar functions, but with SPI replacing the I2C interface. There are 8bit, 10bit or 12bit parts MCP47FEB0x 8bit ...

Diodes Incorporated has introduced a pair of low-power analogue multiplexers that can operate from 10V to 36V or ±5V to ±18V. Supply current for either device is typically 135μA. PS508 is a bi-directional single-pole eight way switch PS509 is a bi-directional dual-pole four-way switch – suitable for 4:1 switching of differential signals Both work across -40°C to +125°C. “The analogue multiplexers that ...
