Automakers are struggling to deliver the first commercially available fully autonomous car (SAE Level 5). There are a lot of vision technologies and sensors available, but fine-tuning them has proved to be challenging. Cars need to “see” objects, moving or stationary, from far away enough to react and make driving decisions. One of the most […]
Inertial Measurement Units: The hidden key to Apollo success, now a MEMS device (Part 2)
Part 1 of this article looked at the classic, highly refined, mature gyroscope-based IMU used for the Apollo moon mission; this part looks at the very different technologies which have largely replaced it. Gyro-based IMU: obsolete, or not? Inertial navigation relies on a stable platform with an orientation which is fixed in space and maintains […]
Multi-channel, mixed-signal RF converter platform boosts call capacity, data throughput for wireless carriers
Analog Devices, Inc. introduced a mixed-signal front-end (MxFE) RF data converter platform that combines high-performance analog and digital signal processing for a range of wireless equipment such as 4G LTE and 5G millimeter-wave (mmWave) radios. ADI’s new AD9081/2 MxFE platform allows manufacturers to install multiband radios in the same footprint as single-band radios, which as […]
DAC carries on-chip reference, SPI interface, gives 14-bit current output
The AD5770R is a 6‑channel, 14‑bit resolution, low noise, programmable current output, digital-to-analog converter (DAC) for photonics control applications. The device incorporates a 1.25 V, on-chip voltage reference, a 2.5 kΩ precision resistor for reference current generation, die temperature, output monitoring functions, a fault alarm, and reset functions. Key Features ► 6-channel, current output DAC […]
Dual, simultaneous sampling, 14‑bit SAR ADC offers differential inputs
The AD7381 is a 14‑bit, pin-compatible, dual simultaneous sampling, high speed, low power, successive approximation register (SAR) analog-to-digital converter (ADC) that operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS. The analog input type is differential, accepts a wide common-mode input voltage, and is sampled and […]

RF Transceiver speeds development of 2G-5G base stations, phased-array radar
Billed as the industry’s widest bandwidth RF transceiver, the ADRV9009 RF transceiver is a single-chip time-domain duplex (TDD) IC delivering twice the bandwidth (200 MHz) of previous-generation devices and replaces as many as 20 components, cutting power in half and package size by 60%. The ADRV9009 meets the rigorous antenna density and expanded network capacity […]
Built-in analog-to-digital converters
There are sensors for a plethora of smart applications that can measure a wide range of parameters (e.g., temperature, light, acceleration, pressure, proximity, etc.). The real world data is analog. Therefore sensors typically provide analog data in the form of voltage (e.g., 0V-5V) and most of the time this data is later transformed into digital […]
PCB layout guidelines and considerations
A Printed Circuit Board (PCB) layout, in its most basic form, is a means to transfer a circuit from a breadboard to a more stable and permanent physical form. Whereas entire books and college coursework have been dedicated to PCB layout, what follows is a short overview of what to consider when making a PCB. […]
