MCP37221 14-Bit Analog-to-Digital Converters

The MCP37221 from Microchip Technology is a 14-bit pipelined ADC with a maximum sampling rate of 200 MSPS. The high accuracy of over 74 dB signal-to-noise ratio (SNR) and over 90 dB spurious free dynamic range (SFDR) enable high precision measurements of fast input signals. The device operates at very low power consumption of 490 mW at 200 MSPS, including LVDS digital I/O. Lower power saving modes are available at 144 mW for standby and 28 mW for shutdown. The MCP37221-200 includes many digital processing features that simplify system design, cost, and power usage. These include 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 serial peripheral interface (SPI). The device is available in the TFBGA-121 and VTLA-124 packages. The TFBGA-121 package is qualified for automotive applications (AEC-Q100). The MCP37221 ADC is ideal for communication instrumentation, cellular base stations, scanners, lidar, and radar applications.
