 | Kit Overview
The EVAL-ADAS3022EDZEVAL-ADAS3022EDZ is an evaluation board for the ADAS3022ADAS3022 16-bit data acquisition system (DAS). This device integrates an 8-channel multiplexer, a high impedance programmable gain instrumentation amplifier (PGIA) stage with a high common-mode rejection, a precision 16-bit successive approximation (no latency) analog-to-digital converter and precision 4.096 V reference offering an aggregate throughput of 1 million samples per second (1 MSPS).
The evaluation board is designed to demonstrate the perform-ance of the ADAS3022ADAS3022 and to provide an easy-to-understand interface for a variety of system applications. A full description of this product is available in the data sheet and should be consulted when utilizing this evaluation board.
The EVAL-ADAS3022EDZEVAL-ADAS3022EDZ board operates in stand alone mode or in conjunction with the Converter Evaluation and Development board EVAL-CED1ZEVAL-CED1Z, a USB-based capture board connected to P4, the 96-pin interface. When operated with the Converter Evaluation and Development board, software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the Converter Evaluation and Development board.
On-board components include a high precision, buffered band gap 4.096 V reference (ADR434ADR434), reference buffers (AD8032AD8032), passive signal conditioning circuitry, and an FPGA for deserializing the serial conversion results and configuring the ADAS3022ADAS3022 via a 4-wire serial interface. The P3 connector allows users to test their own interface with or without the optional Altera FPGA, U6 (programmed using the P2 and passive serial EEPROM, U5).

Software Tools
ADAS3022 Evaluation Board Software
The ADAS3022 evaluation board connects to the EVAL-CED1Z converter evaluation and demonstration board. The EVAL-CED1Z board is the controller board, which is the communi-cation link between the PC and the main evaluation board. The software for the EVAL-CED1Z is used to perform the following tests:
- Histogram tests for determining code transition noise (dc)
- Fast Fourier transforms (FFT) for signal-to-noise ratio (SNR), SNR and distortion (SINAD), total harmonic distortion (THD), and spurious free dynamic range (SFDR)
- Time domain analysis
