As a high-speed, high - resolution data acquisition syste , power supply must be well regulated to control additional high-frequency noise (ripple). AD684 power connection in figure can well meet above requirements, while enable to transmit instantaneous current to the device. In order to achieve the rated accuracy and dynamic performance, the power supply decoupling capacitors must be directly connected between the positive power supplyfeet and the negative feet to ground, and typically itconnects 0.1μF ceramic capacitorsbetween VCC and VEE to ground.
