Fast precision A/D converters feature low power

The MCP37DX0-200 and MCP372X0-200 12- and 14-bit pipelined high-speed A/D converters sample at up to 200 Ms/s. The devices feature over 67 dB SNR and over 96 dB SFDR while consuming only 338 mW including LVDS digital I/O for the 12-bit devices and 348 mW for the 14-bit devices. They use just 80 mw in standby.

The ICs include various DSP functions that simplify system design as well as decimation filters for improved SNR and phase, offset, and gain adjustment. The MCP37DX0-200 includes a digital down-converter. The 12-bit devices include a noise-shaping requantizer which enables users to lower the noise within a given band of interest. The come in 124-lead VTLA packages at prices ranging from $25.78 to $53.87 ea/5,000.
