Analog DevicesEVAL-AD7400AEDZDatenkonvertierung, Entwicklungsplatinen und -kits

the evaluation board for the AD7400A and AD7401A. The AD7400A and AD7401A are second-order, sigma-delta (Σ-Δ) modulators that convert an analog input signal into a high speed, 1-bit data stream with on-chip digital isolation based on the Analog Devices Inc., iCoupler® technol-ogy. The AD7400A and AD7401A operate from a 5 V power supply and accept a differential input signal of ±200 mV (±320 mV full scale). The analog input is continuously sampled by the analog modulator, eliminating the need for external sample-and-hold circuitry. The input information is contained in the output stream as a density of ones with a data rate of 10 MHz. The original information can be reconstructed with an appro-priate digital filter. The serial I/O can use a 5 V or a 3 V supply (VDD2). Full details on the AD7400A and AD7401A are available in the AD7400A and AD7401A data sheets, which are available from Analog Devices and should be consulted in conjunction with this data sheet when using the evaluation board.
On-board components include two AD797 analog op amps for buffering the differential analog input to the AD7400A and AD7401A. Various link options are explained in the Link Options section. Interface to this board using a standard 2-row 34-pin SPORT connector. This SPORT connector is compatible with the EVAL-CED1Z, which is available from Analog Devices. External sockets are also provided for signals.
