The integrated features offered by the the ADCs enable reliable of aerospace and defence, industrial and automotive systems
System designers have limited options for small, robust, feature-rich high-speed ADCs for extended-temperature operation.
Therefore, Microchip Technology has filled this gap with its MCP37Dx1-80 family of ADCs and combines 80 MSPS in a choice of 12, 14 and 16-bit resolutions, integrated digital features and qualifications to a high-temperature range. The ADCs enable a wide variety of aerospace and defence, industrial and automotive systems that require a high level of reliability.
Key Device Features
⦁ Robust and reliable design architecture: The ADCs operate over a temperature range of -40 degrees Celsius to +125 degrees Celsius, making 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 the 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.
“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.”
The 12-bit MCP37D11-80, 14-bit MCP37D21-80 and 16-bit MCP37D31-80 ADCs are industry qualified to AEC-Q100 grade 1 standard and available for volume production. Evaluation boards with graphical user interface (GUI) and firmware are also available for Microchip’s 12,14 and 16-bit MCP37Dx1-80 ADCs as development aid for customers.
