AD7767BRUZ-RL7

AD7767 is a high performance, 24-bit, oversampled SAR analog-to-digital converter (ADC). It is Ideal for ultralow power data acquisition (such as PCI- and USB-based systems), this device provide 24-bit resolution. The combination of exceptional SNR, wide dynamic range, and outstanding dc accuracy make the device ideally suited for measuring small signal changes over a wide dynamic range. This is particularly suitable for applications where small changes on the input is measured on larger AC or DC signals. In such an application, the device accurately gather both ac and dc information. It include an on-board digital filter (complete with linear phase response) that acts to eliminate out-of-band noise by filtering the oversampled input voltage. It is widely used in application such as low power PCI/USB data acquisition systems, low power wireless acquisition systems, vibration analysis, instrumentation, high precision medical acquisition etc.
