MCP37221/D21: 200Msps, 14-Bit Low Power ADC with 8-Channel MUX
The MCP37x21-200 is a 14-bit pipelined A/D converter with a maximum sampling rate of 200Msps. The high accuracy of over 74dB Signal-to-Noise Ratio (SNR) and over 90dB Spurious Free Dynamic Range (SFDR) enable high precision measurements of fast input signals. The device operates at very low power consumption of 490mW at 200Msps including LVDS digital I/O. Lower power saving modes are available at 80mW for stand-by and 33mW for shutdown. The MCP37x21-200 includes many digital processing features like decimation filters for improved SNR, individual phase, offset and gain adjustment and a fractional delay recovery for time-delay corrections in multi-channel modes.
