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 of the 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, autonomous driving, 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, while a digital down-converter supports communication designs and a noise-shaping requantizer in the 12-bit ADCs improves accuracy and performance. 
•    Small size: Their compact 8 mm x 8 mm 121-pin ball grid array packages with 0.65 mm pitch also include built-in reference decoupling capacitors that further reduce cost and overall footprint by eliminating the need for external bypass capacitors.

Evaluation boards with graphical user interface and firmware are available for Microchip’s 12-,14- and 16-bit MCP37Dx1-80 ADCs as a development aid for customers.

The 12-bit MCP37D11-80, 14-bit MCP37D21-80 and 16-bit MCP37D31-80 ADCs are available for volume production now. They are priced at $17.45, $29.87 and $40.42 each, respectively, in 10,000-unit volumes.
