描述 Description

The MCP37D31-80 is a 16-bit pipelined A/D converter with a maximum sampling rate of 80 Msps. The high accuracy of over 73.9 dB Signal-to-Noise Ratio (SNR) and over 93 dB Spurious Free Dynamic Range (SFDR) enable high precision measurements of fast input signals. The device operates at very low power consumption of 329 mW at 80 Msps including LVDS digital I/O. Lower power saving modes are available at 79 mW for Standby and 22 mW for Shutdown. The MCP37D31-80 includes many digital processing features that simplify system design, cost and power usage. These include an integrated digital down-converter with onboard NCO, decimation filters for improved SNR, individual phase, offset and gain adjustment and a fractional delay recovery for time-delay corrections in multi-channel modes. Data is available through the serial DDR LVDS or parallel CMOS interface and configured via SPI. The device is available in the TFBGA-121 package.?TFBGA-121 package is qualified for automotive applications (AEC-Q100).
