Analogue / Linear / Mixed Signal ICs

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 ...

Maxim has introduced a chip to interface devices equipped with I2C or SPI bus connections to its ‘1-wire’ bus. Called DS28E18, it is intended to knock cost out of networks that connecting I2C and SPI sensors to a host by reducing the number of copper wires needed for up to 10 nodes to two wires. Busses over 100m long are ...

Diodes has announced its first precision op-amp, the chopper-stabilised dual AS2333, which has rail-to-rail inputs and outputs and operates over 1.8V to 5.5V (or ±0.9V to ±2.75V) and -40°C to +125°C. Typical figures are 8µV input offset, 0.02µV/°C drift over time and temperature, 120dB common-mode rejection ratio and 130dB open-loop gain. The amplifiers have a bandwidth 350kHz and typically slew ...

Rohm is claiming “industry’s first high-speed op-amp that eliminates oscillation due to load capacitances” for its 10V/μs BD77501G – which is not quite true unless some further caveats are added as, for example, ADI’s ‘C-Load’ op-amps are stable with any capacitance – LT1364 can hit 1,000V/μs. Rohm’s branding for capacitive tolerance is ‘Nano Cap’. BD77501G is a ground sense CMOS op amp ...

Analog Devices has introduced RS-485 and RS-422 transceivers that can withstand 5.7kVrms and ±15kV ESD. “The transceivers’ simplified PCB layout and small form factor pack more functionality into space constrained applications than the previous generation,” said ADI. There will be four products: ADM2867E 25Mbit/s full duplex, separate driver and receiver cable inversions pins ADM2865E 25Mbit/shalf duplex, combined cable inversion pin ...
