4-Channel, 16-Bit, Continuous Time Data Acquisition ADC
The front-end circuitry is designed to allow direct connection to an MMIC output with few external passive components. The ADAR7251 eliminates the need for a high order antialiasing filter, driver op amps, and external bipolar supplies. The ADAR7251 also offers precise channel-to-channel drift matching.
The ADAR7251 features an on-chip phase-locked loop (PLL) that allows a range of clock frequencies for flexibility in the system. The CONV_START input and DATA_READY output signals synchronize the ADC with an external ramp for applications such as FSK-FMCW radar.
The ADAR7251 supports serial and parallel interfaces at programmable sample rates from 300 kSPS to 1.8 MSPS, as well as easy connections to digital signal processors (DSPs) and microcontroller units (MCUs) in the system.

Evaluation Board Overview
The ADAR7251 mini board allows a user to program, debug and evaluate the performance of the ADAR7251. Its small form factor makes it the ideal hardware for evaluation of Radar systems using the easy interface to MMIC and DSP. The MMIC and DSP Board (SDP-B) are available from the www.analog.com or contact ADI sales. The GUI for the board can be downloaded.
