Featuring high performance of over 67dB SNR and over 96dB SFDR, two families of high-speed ADCs have been introduced by Microchip Technology. The MCP37DX0-200 and MCP372X0-200 families feature 12- and 14- bit pipelined ADCs with a maximum sampling rate of 200MS/s and enable high-precision measurements of fast input signals.

These families operate at very low-power consumption of 338mW at 200MS/s including LVDS digital I/O for the 12-bit devices and 348mW for the 14-bit devices. Lower power-saving modes are available at 80mW for standby and 33mW for shutdown.

The MCP37DX0-200 and MCP372X0-200 include various digital processing features that simplify system design, cost and power usage for designers. These families also include decimation filters for improved SNR and phase, offset and gain adjustment. Data is available through the serial DDR LVDS or parallel CMOS interface and configured via SPI. An integrated digital down-converter is included in the MCP37DX0-200 family making it suited for communications applications. The 12-bit devices include an integrated noise-shaping requantiser which enables users to lower the noise within a given band of interest for improved accuracy and performance. These families are targeted for applications in the communications markets such as base stations, test equipment and IF receivers, among others.

The MCP37DX0-200 and MCP372X0-200 are supported by Microchip’s MCP37XX0-200 14-bit 200MS/s VTLA Evaluation Board (ADM00652) priced at $450.00 and MCP37XXX High-Speed ADC Data Capture Card (ADM00506) priced at $599.00.

The MCP37DX0-200 and MCP372X0-200 families are available now for sampling and volume production in 124-lead VTLA packages.
