Analogue / Linear / Mixed Signal ICs

Diodes has introduced 1.8V 10Gbit/s line re-drivers for USB Type-C and DisplayPort 2.0 connections. PI2DPX1066 and PI2DPX1217 are 4-to-4 devices for USB Type-C with 900mV max swing, and support DisplayPort for host CPUs with integrated USB – DisplayPort crossbar switches. Both have four modes: SuperSpeed USB 10Gbps SuperSpeed USB 20Gbps SuperSpeed USB 10Gbps or 2-lane DP1.4/DP2.0 (UHBR10) 4-lane DP1.4/DP2.0 (UHBR10) Default ...

Diodes has created its first automotive-compliant USB 2.0 passive signal mux-demux switches with over-voltage signal and power rail protection. PI3USB4000DQ is a 2:1/1:2 switch for differential bi-directional DPDT PI3USB4002AQ is a 1:1 switch for differential bi-directional DPST switching 24Vdc withstanding is provided on one high-speed data port (‘C0’ pins), enabling them to tolerate shorts between D± and Vbus on both USB and ...

Nexperia has announced a range of ESD protection devices aimed at protecting high-speed interfaces in automotive applications, especially in-vehicle networks for infotainment and communications. There are 12 four-channel devices in the PESD4USBx series, according to the company, with headline figures of  0.25pF line capacitance, <0.05pF line matching and 0.4Ω dynamic resistance. That said, only eight devices show up in the ...

Data Modul is aiming at industrial displays from 12.1 to 23.8in with a projected capacitive (PCap) touch controller PCB built around Microchip’s TD series of touch controller chips. The mXT2952TD touch controller board is compatible with Data Module’s earlier mXT2952T2, but includes differential mutual sensing to increase signal-to-noise ratio. “Neither thick gloves up to 5mm nor cover glasses up to 10mm ...

Infineon is claiming a first: AEC-Q103 qualification for a MEMS microphone. It is the IM67D130A, which operates over -40°C to +105°C and has an acoustic overload point (AOP) of 130dB SPL which “allows the microphone to capture distortion-free audio signals in loud environments. Because of that, it can be placed inside or outside of the vehicle”, said the company. It “is ...

Rohm has announced a 32bit mono/stereo Hi-Fi DAC, claiming for it a typical signal to noise ratio of 130dB and -115dB THD+noise. Called BD34301EKV, it can accept PCIM inputs from 32 to 768kHz and DSD at 2.8, 5.6, 11.2 or 22.4MHz. FIR filters are provided for: PCIM sharp roll-off, PCIM slow roll-off and DSD. The two outputs each provide differential currents, which ...

STMicroelectronics has signed a deal with German MEMS mirror start-up OQmented to develop technology for augmented reality and 3D laser scanning. ST already makes MEMS sensors, actuators, drivers and controllers. OQmented has a patented way to vacuum-encapsulate MEMS using hermetic glass bubbles to eliminates environmental contaminants with minimal light-refraction – branded Bubble MEMS. “Vacuum sealing is a key element for ...

Melexis has introduced a 16 channel RGB LED driver for vehicle interior lighting, capable of real-time colour drift compensation to a delta UV of <0.01% “to eliminate any distinguishable differences between LEDs”, claims the company. What measurement technique does the device, called MLX81117, use to get such close compensation? “It is basically a very exact measurement of voltages and, or, ...

STMicroelectronics has created isolated second-order sigma-delta modulators for industrial applications. They convert an analogue input signal up to ±320mV full-scale into a 1bit digital data stream at up to 25Msample/s. Resolution is 16bit (ENOB typically 13bit) and signal-to-noise ratio is 86dB. “The embedded galvanic-isolation technology of these devices eliminates the degradation associated with converters, as well as lowering power consumption and ...

Vishay has announced power stages for synchronous buck converters that allow a logic-level PWM signal to control 70, 80 or 100A outputs. There are six parts that will handle inputs from 4.5 – 16V (see table below) then four that will handle 4.5 – 21V – there is no 100A option in the higher voltage devices. Different versions are tuned for 3.3 ...
