AD8224-EVALZ

精密，双通道， JFET输入，轨到轨仪表放大器 Precision, Dual-Channel, JFET Input Rail-to-Rail Instrumentation Amplifier

The is an evaluation board to evaluate the performance of AD8224 single supply, JFET input instrumentation amplifier. It has two AD8224 instrumentation amplifier circuits, one circuit is configured for dual channel operation, and the other is configured for single channel, differential output operation. The inputs, outputs, references, and supplies are routed to screw terminals for easy connectivity. The PCB board has four layers. The top and bottom layers are used for routing, and the two internal layers are ground planes. The ground plane was removed underneath the RG resistors. This is a precaution against any capacitance mismatch at the RGx pins that may affect ac CMRR.
