Analogue / Linear / Mixed Signal ICs

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with the amplifier compatible with both ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. BUF802 signal paths “Oscilloscope manufacturers have got a choice: develop a discrete JFET input stage and risk limited performance, or develop their own asic,” TI general manager of linear amplifiers John Caldwell told Electronics Weekly. Developing a custom asic “is a massive undertaking where ...

TouchNetix has got automotive AEC-Q100-6 qualification for its AX112 touch controller IC, which also includes hover sensing, force sensing and the control of haptic response. “Touchscreens based on the AX112 can support features such as pre-select, zoom-on-approach, dial-on-display and integrated haptic feedback without the need for additional hardware,” said the company. It “also supports the operation of touchscreens with variable thickness, ...

u-blox is aiming at centimeter-level positioning for industrial navigation and robotics with a pair of GNSS (global navigation satellite system) correction receivers and a corresponding up-grade to its existing ZED-F9P high-precision GNSS receiver module. The correction receivers stream correction data from communication satellites. The “new correction service receivers offer broad geographical coverage across Europe, continental US and Japan,” according to the ...

Diodes has introduced a digital stereo audio amplifier with built-in boost converter that allows 8+8W to be delivered from one Li-ion cell and 12+12W from two cells in series. Called PAM8965, more detailed figures are: One cell (Vbatt = 3.7V) 8W/channel at 10% THD+N (6Ω load 1kHz) 6.4W/channel at 1% THD+N (6Ω load 1kHz) 20mA quiescent 700nA shutdown Two cells ...

ADA4355 from Analog Devices is a current-input digital-output converter works with pulses down to 10ns for time-of-flight measurements using photo diodes. In a 12 x 6mm BGA package, the IC is actually a hybrid module combining transimpedance amplifier, analogue low-pass filter and 14bit 125Msample/s ADC converter. The output is through two serial LVDS (low-voltage differential signalling) lanes at up to 1Gbit/s/lane. The data clock ...

For an automotive three-phase fan motor driver, Allegro has picked a control algorithm for quiet running in electric vehicles. Called A89307, it uses field-oriented control to drive continuous sinusoidal current to the load. “By design, electric and hybrid vehicles are quieter than traditional models with internal combustion engines, especially when they’re stopped, and drivers are becoming increasingly sensitive to noise created ...

Microchip has announced an automotive voltage reference with 7ppm/°C maximum temperature coefficient. Called MCP1502, it works over -40 to +125°C and is qualified to AEC-Q100 Grade 1. The company is keen to mention the parts lineage: “MCP1502 is based on the already-proven MCP1501 Vref architecture, which has been in the market for more than five years.” It is available in eight ...

Believed to be the first electromigration/voltage drop (EM/IR) tool for both analogue and digital methodologies, mPower has been released by Siemens Digital Industries. The tool marks Siemens’ entry into the IC power analysis market, capable of power integrity analysis for analogue, digital and mixed-signal IC designs. It is also scalable and uses industry standard inputs and interfaces. Power integrity analysis ...

Analog Devices is aiming at wearable patient monitoring devices with an analogue front-end for four vital signs: electrocardiogram, heart rate, blood-oxygen saturation and respiration rate. The chip, MAX86178, does this with three channels, one each for: photodiodes (optical PPG for blood oxygen and heart rate), voltages (electrocardiogram (‘ECG’ or ‘EKG’) and alternative heart rate) and bio-impedance (‘bio-z’ for respiration rate) Optical ...
