80MSPS ADCs Support High Temperatures

Microchip Technology has announced its MCP37Dx1-80 family, the company’s second pipelined ADC offering and first to combine 80Msample/s 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. Microchip’s MCP37Dx1-80 ADCs are designed enable a wide variety of aerospace and defense, industrial and automotive systems that require a high level of reliability.

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, says Microchip. This makes them well suited for demanding applications such as Advanced Driver Assistance Systems (ADAS), autonomous driving, Low Earth Orbit (LEO) satellites and test and measurement equipment. The device offers 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.

The MCP37Dx1-80 ADCs feature compact 8mm x 8mm 121-pin ball grid array (BGA) packages with 0.65mm pitch. They 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 (GUI) 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.
