Analog DevicesEVAL-ADCMP580BCPZ开发套件和工具

Evaluation Board t is fabricated using a high quality dielectric material between the ground plane and signal layers in order to maintain high signal integrity. All input and output signals are brought on to the board with 2.9 mm RF connectors, and transmission line paths are kept as close to 50 Ω as possible.

The AD7690 is an 18-bit, successive approximation, analog-todigital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 18-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. On the CNV rising edge, it samples the voltage difference between the IN+ and IN− pins. The voltages on these pins swing in opposite phase between 0 V and REF. The reference voltage, REF, is applied externally and can be set up to the supply voltage.
