High-integration ADCs offer 14-/12-bit resolution, 200 Msps conversion
The converters offer over 67 dB signal-to-noise ratio (SNR) and over 96 dB spurious free dynamic range (SFDR). These families operate at very low-power consumption of 338 mW at 200 Msps including LVDS digital I/O for the 12-bit devices and 348 mW for the 14-bit devices. Lower power-saving modes are available at 80 mW for standby and 33 mW 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 applicable to communications functions. 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 200 Msps VTLA Evaluation Board (Part # ADM00652, $450.00), and MCP37XXX High-Speed ADC Data Capture Card (Part # ADM00506, $599.00).
The MCP37DX0-200 and MCP372X0-200 families are available now for sampling and volume production in 124-lead VTLA packages, at prices ranging from $25.78 to $53.87 each (5000).
