Analog Devices Inc. EVAL-ADAR7251Z

Overview

EVAL-ADAR7251Z from Analog Devices is an evaluation board designed to program, debug, and characterize the ADAR7251 - a 16-bit delta-sigma ADC for 24 GHz/77 GHz automotive radar systems - using direct MMIC and SDP-B board interfacing on a compact 4-layer PCB (3.1 × 2.5 in).

For engineers reviewing the EVAL-ADAR7251Z datasheet, EVAL-ADAR7251Z pinout, EVAL-ADAR7251Z application, or EVAL-ADAR7251Z equivalent, key considerations include its 80-pin MMIC interface, 120-pin SDP-B connector, onboard 5 V power supply support, test point access to ADAR7251 signals, and RoHS-compliant construction.

Technical Context

The EVAL-ADAR7251Z serves as a hardware platform for functional validation and performance benchmarking of the ADAR7251 ADC under real-world RF front-end conditions. It provides direct signal routing from MMICs to the ADC input and supports digital capture via the SDP-B interface for FFT-based radar waveform analysis.

Board-level design includes dedicated power indicator and general-purpose LEDs, reset and download push buttons, and test points aligned to all critical ADAR7251 pins - enabling low-overhead probing without soldering or adapter modification.

FAQ

What is the primary function of the EVAL-ADAR7251Z?

The EVAL-ADAR7251Z is an evaluation board that enables programming, debugging, and performance characterization of the ADAR7251 - a 16-bit delta-sigma ADC targeting 24 GHz and 77 GHz radar applications. It is not a standalone IC but a hardware platform supporting signal acquisition, power sequencing, and digital interface to host systems via SDP-B.

Does the EVAL-ADAR7251Z include the ADAR7251 IC?

Yes, the EVAL-ADAR7251Z board includes the ADAR7251 ADC mounted in its native 7 mm × 7 mm LFCSP-SS package. The board is pre-assembled with the device and ready for immediate connection to MMICs and SDP-B for functional evaluation.

What power supply does the EVAL-ADAR7251Z require?

The EVAL-ADAR7251Z operates from a single 5 V supply, delivered via the included 5 V adapter. No additional voltage rails or regulators are needed - all internal power domains for the ADAR7251 and supporting circuitry are generated onboard.

Can the EVAL-ADAR7251Z be used without the SDP-B board?

No - the EVAL-ADAR7251Z relies on the SDP-B board for digital communication, firmware loading, and data capture. The 120-pin interface is mandatory for configuring the ADAR7251 and retrieving ADC output; standalone analog operation without SDP-B is not supported.

Are test points provided for all ADAR7251 pins on the EVAL-ADAR7251Z?

Yes, the EVAL-ADAR7251Z features dedicated test points aligned to every pin of the ADAR7251 IC. This allows direct oscilloscope or logic analyzer access to analog inputs, reference voltages, clock signals, and digital outputs without soldering or modifying the board.
