TI claims industry’s fastest 14bit ADC


Texas instruments is claiming the fastest 14bit ADC yet with one that works at 3Gsample/s, delivering “an instantaneous 1.5GHz-per-channel bandwidth, enabling engineers to implement wideband in-phase and quadrature-component receivers beyond 2.5 GHz”, said the firm. The dual-channel ADC32RF45 can be used for direct RF signal conversion up to 4GHz,” said TI. “The first in a new data converter family, it eliminates up ...

USB-C audio codec handles connector switching

Connexant USB C headset

Conexant has announced two USB-C audio codecs for phone headsets and docking stations. Both CX20985 and CX20899 feature a built-in, four-conductor headset jack interface that supports headphone/headset auto detection, as well as auto-switching between OMTP and CTIA-style headsets without the need for external components. Featuring a stereo 24bit DAC and ADC for music and voice communication applications, CX20985 supports sampling rates ...

Modules combine Microchip touch and 3D gesture sensing

Microchip touch gesture display

Microchip has revealed a pair of linked peripheral modules that can combined projected multi-touch 2D and 3D gesture sensing for microcontrollers. Developed with Silicon Integrated Systems (SiS), both are capacitive, with the 3D sensing based on strip electrodes along each edge of the display. A version of its GestIC technology, it can track a hand up to 200mm from the ...

Maxim chip will connect industrial IoT sensor networks


Maxim Integrated has introduced dual-channel transceiver for sensor networks in a small form-factor for industrial IoT designs. The MAX14827 dual-channel, 250mA transceiver meets the requirements of IO-Link sensor networks, and it has a high-voltage function for industrial sensors, including drivers and regulators. For sensors that use a microcontroller, a SPI interface is available with extensive diagnostics. For IO-Link operation, a ...

Clock distribution IC has 3 independent outputs


Linear Technology has introduced a 1.8GHz clock distribution IC with three independent outputs, each with its own divider and phase delay. The device, the LTC6954, has a jitter specification of less than 20femto-second (RMS) additive jitter over the 12kHz to 20MHz bandwidth. This minimises the noise the chip introduces when dividing and distributing its input clock. There are four versions of the ...

First CXPI-compatible transceiver IC

Rohm BD41000F CXPI

Rohm is claiming a first, with a transceiver IC for the CXPI automotive communication protocol – aimed at body control applications such as steering wheel switches, air conditioning and instrument panels. The BiCDMOS chip, called BD41000FJ-C, enables multiplexing between electronic control units (ECUs) to reduce wiring (see diagram). “To decrease weight, many systems adopt LIN for multiplex communication,” said Rohm, claiming: ...

One chip MCU thermocouple interface

Microchip MCP9600

Microchip has released a thermocouple to digital converter accurate to ±1.5°C, claims the firm (0 to +85°C ambient). Called MCP9600, it includes junction compensation, needs no external components except a decoupling capacitor, and works with thermocouple Types K, J, T, N, S, E, B and R (NIST ITS-90). As well as a digital output via I2C, it has four logic-level ...

Monitor PSU voltage and current via a single pin

Microchip PAC1921

Can a microcontroller monitor PSU voltage and current through a single analogue pin? Yes, now that Microchip has introduced its PAC1921, which does just that. The trick is that it also has a serial bus that tells the analogue output whether it is representing passing current or rail voltage at any given moment. The two-wire serial I2C-compatible bus follows the SMBus power ...

Programmable analogue ICs are route to cost-efficiency


Design reuse can apply to analogue circuits as much as to digital, writes Steve Logan, who describes what programmable analogue devices can offer a designer. What would you, an IC system designer, put into an ideal programmable analog device? Start with 20 ports of programmable ADCs, DACs, digital IOs, switches, level translators, and internal and external temperature-sensor connections. Make any ...
