Microchip Expands Solutions With New High-Speed Analog-to-Digital Converter Family

Reading time ( words)

System designers have limited options for small, robust, feature-rich high-speed ADCs for extended-temperature operation. Microchip Technology Inc. announced it has filled this gap with its MCP37Dx1-80 family, the company’s second pipelined ADC offering and first to combine 80 MSPS in a choice of 12-, 14- and 16-bit resolutions, integrated digital features and qualification to a higher temperature range, including Automotive Electronics Council (AEC) Q100. 

“Our latest ADCs meet growing customer demand for robust devices that can be used in high-temperature applications and offer integrated digital processing functions that simplify design and reduce overall development costs,” said Bryan Liddiard, Vice President, Mixed-Signal and Linear division at Microchip. “The MCP37Dx1-80 family joins Microchip’s 200 MSPS ADCs to expand our high-speed offering into a much broader range of system design concepts.”

Microchip’s MCP37Dx1-80 ADCs enable a wide variety of aerospace and defense, industrial and automotive systems that require a high level of reliability. Key ADC device features include:

• Robust and reliable design architecture: The ADCs operate over a -40°C to +125°C temperature range and are among the few high-speed ADCs in the industry qualified to AEC-Q100 grade 1 standards. This makes them ideal for demanding applications such as Advanced Driver Assistance Systems (ADAS), autonomous driving, Low Earth Orbit (LEO) satellites and test and measurement equipment.
• Integrated digital features that eliminate external components and reduce MCU post-processing: Decimation filters improve signal-to-noise ratio (SNR), while a digital down-converter (DDC) supports communication designs and a noise-shaping requantizer in the 12-bit ADCs improves accuracy and performance.
• Small size: Their compact 8mm x 8mm 121-pin ball grid array (BGA) packages with 0.65mm pitch also include built-in reference decoupling capacitors that further reduce cost and overall footprint by eliminating the need for external bypass capacitors.

A joint program between NASA and its counterparts in Europe (ESA) and Canada (CSA), Webb will observe the beginnings of our Universe by reaching back in time to just a few hundred million years after the Big Bang. It will also observe exoplanets – planets outside the Solar System – that are comparable to our own, as well as the formation and evolution of stars and galaxies. The ultimate aim of this successor to the iconic Hubble space telescope is to discover galaxies that reach back to the relative beginnings of the Universe. This state-of-the-art time machine is expected to revolutionize all aspects of modern astronomy. It will unveil the hidden side of the Universe, namely stars enveloped in clouds of dust, molecules in the atmosphere of other worlds, and the light issuing from the first stars and galaxies.

Like a cancer that spreads untreated until it becomes an urgent problem, the U.S. defense community is facing a small but growing problem that is increasingly undermining U.S. military readiness and technological dominance. The problem is lead—specifically, the lead-alloy solders that traditionally have been used to attach electronic components to printed circuit boards (PCBs). Over the last 15 years, the commercial electronics industry has shifted to lead-free solders, prompted by environmental health regulations in Europe and elsewhere. However, the U.S. Department of Defense (DoD) and its contractors never made the switch and are still heavily reliant on leaded solders. Now, leaded electronics are becoming harder to find and more outdated.
