Product Details

The EV-ADuM7802-8FMCZ is a fully-featured evaluation board that allows the user to evaluate all features of the ADuM7802 isolated analog-to-digital converter (ADC) with Σ-Δ modulated bit stream output. The ZedBoard Zynq-7000 controller board controls the EV-ADuM7802-8FMCZ by the J9 connector and through the USB port of a PC using the ACE Software. The ACE Software is available to download on the ACE Software page.

On-board components include an isolated, 5kV, isoPower^® DC‑to- DC converter (the ADuM6028-5), a 5V, low noise, low dropout (LDO) regulator (the ADP7104), and a 200mA, 40V, low noise, LDO regulator (the ADP7142).

This user guide explains how to use the EV-ADuM7802-8FMCZ to evaluate the ADuM7802. The ADuM7802 is a high-performance isolated ADC with a second-order Σ-Δ modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc., iCoupler^® technology. The device operates from a 4.0V to 5.5V power supply range (high-side supply voltage, V_DD1) and accepts a pseudo-differential input signal of ±50mV (±64mV full-scale). The pseudo-differential input is ideally suited for shunt-resistor current monitoring in high voltage applications where galvanic isolation is required.

The analog input is continuously sampled by a high-performance analog modulator and converted to a pulse density modulation digital output stream with a data rate of up to 25MHz. The analog input can be reconstructed with an appropriate sinc3 digital filter to achieve an 84dB signal-to-noise ratio (SNR) at 97.6kSPS with a 256 decimation rate and a 25MHz input clock. The serial input and output operates from a 3V to a 5.5V supply (controller-side supply voltage, V_DD2).
