EVAL-CN0225-SDPZ

EVAL-CN0225-SDPZ is a CN0225 circuit evaluation board. The circuit is a complete and highly integrated analogue front-end industrial level signal conditioner that uses only two active components to drive an AD7687 differential input 16-bit PulSAR ADC: the AD8295 precision in-amp (with 2 on-chip auxiliary op-amps) and the AD8275 level translator/ADC driver. An ADR431 low noise 2.5V XFET® reference supplies the voltage reference for ADC. The circuit provides a high impedance instrumentation amplifier input with high CMR, level shifting, attenuation, and differential conversion, with only two analogue components. Because of the high level of integration, the circuit saves printed circuit board space and offers a cost effective solution for industrial application. Signal levels of up to ±10V are typical in process control and industrial automation systems. With smaller signal inputs from sensors such as thermocouples and load cells, large common mode voltage swings are often encountered.

• Evaluation board connects to SDP-B controller board (EVAL-SDP-CB1Z) through 120-pin connector
