 | Kit Overview
The Analog Devices EVAL-AD7678EDZEVAL-AD7678EDZ is a fully featured evaluation Kit for the AD7678AD7678. This board operates in stand alone mode or in conjunction with the Converter Evaluation and Development board, EVAL-CED1ZEVAL-CED1Z. 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.
The EVAL-AD7678EDZEVAL-AD7678EDZ is an evaluation board for the 48 lead AD7678AD7678 18- bit PulSAR
The evaluation board is ideal for use with Analog Devices USB based Converter and Evaluation Development EVAL-CED1ZEVAL-CED1Z, (CED) or as a stand-alone system. Since many newer PC’s do not offer a parallel port along with overcomplicated BIOS port settings, the CED board is strongly recommended.
The design offers the flexibility of applying external control signals and is capable of generating conversion results on parallel 18-bit wide buffered outputs. On-board components include a high precision band gap reference, reference buffers, a signal conditioning circuit with two op-amps and digital logic. The EVAL-AD7678EDZEVAL-AD7678EDZ interfaces to the CED capture board with a 96-pin DIN connector. A 40-pin IDC connector is used for parallel output, and test points are provided for the serial port. SMB connectors are provided for the low noise analog signal source, and for an externally generated CNVST (convert start input).
The AD7678AD7678 is an 18-bit, 100 kSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates on a single 5 V power supply. The part contains a high speed 18-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports.
Key Applications: CT scanners, High dynamic data acquisition, Geophone and hydrophone sensors, Σ-Δ replacement (low power, multichannel), Instrumentation, Spectrum analysis Medical instruments | |||||||||||
