Mixed Signal/Analog

  CML Microcircuits announces that it has added a wideband mode to the CMX983 AFE IC that bridges the gap between a digital radio’s RF section and the DSP/FPGA. The 50kHz wideband mode opens up new high speed data application areas in satellite and terrestrial wireless telemetry systems.

Enabling battery-powered, high performance broadband transmitters operating from 700MHz to 6GHz, Linear Technology introduces a low power I/Q modulator. The LTC5589 is powered by a single 2.7 to 3.6V supply and draws only 29.5mA current. According to the manufacturer, this is 50% lower power consumption than other solutions.

A 16-bit, 5MS/s SAR (Successive Approximation Register) ADC with a wide rail-to-rail input common mode range, the LTC2311-16, has been introduced by Linear Technology. The LTC2311-16 features a flexible differential input that accepts analogue signals up to the Nyquist frequency. This provides direct conversion of a variety of signal types while maintaining a good SNR of 81.6dB with a 2.2MHz input signal and achieving a high CMRR of 85dB for the ...

  Offering a new route to next-gen active headphone development, Dialog Semiconductor’s SmartBeat open audio platform IC for active headphones combines extremely low power consumption with impressive processing performance in a small 0.4mm pitch WLCSP.

Featuring a dual-coil architecture that automatically compensates for variations in temperature and component ageing, Texas Instruments has introduced what it claims to be the industry's first differential inductive switch. The LDC0851 detects the presence or absence of conductive material by using a simple coil drawn on a PCB.

Voice interfaces are increasingly popular and ubiquitous in today’s life environment, ranging from well-known teleconferencing systems to upcoming connected natural speech enabled personal assistants. Such new applications are based on a networked topology where processing is distributed on multiple nodes.

  The latest addition to Exar's family of AFE sensor interfaces, the XR18910, integrates high channel count and functionality in a tiny 3.5x3.5mm footprint. Providing 14-bit signal path linearity, the device is designed to connect analog sensors to an MCU or FPGA with an embedded ADC.


The ADS1257 low-noise analogue-to-digital converter (ADC) from Texas Instruments is now available from Mouser Electronics. The four-channel, 24‑bit, delta-sigma ADC with a low-noise programmable gain amplifier (PGA) comes in a small 20-pin, 5mm × 5mm VQFN package. The combination of integration, high conversion rate, and 24-bit resolution together in a small package makes the device ideally suited for space-constrained applications.

XMOS has announced what is claimed as the world’s most flexible microphone aggregation solution for Voice User Interfaces (VUIs) in smart home applications. With the ability to aggregate up to 32 MEMS microphones, the xCORE Array Microphone offers USB and I2S backhaul, enabling a new class of array microphones to be created.

Promising to bring the benefits of ANC (Active Noise Cancellation) to mass-market headphones, ams unveils the compact, cost-effective AS3412 speaker driver. This device extends the manufacturer's family of ANC speaker drivers, drawing on the proprietary analogue noise cancellation technology developed by ams and in use by many of the world’s leading audio equipment manufacturers.
