AD7768-4BSTZ-RL

AD7768-4BSTZ-RL is a 4-channel 24bit, simultaneous sampling, sigma-delta (Σ-Δ) analogue-to-digital converter (ADC). This device has a Σ-Δ modulator and digital filter per channel, which enables synchronized sampling of ac and dc signals. The user can trade off input bandwidth, output data rate, and power dissipation, and select one of three power modes to optimize for noise targets and power consumption. The flexibility of the device allows them to become reusable platforms for low power dc and high performance ac measurement modules. It is used in applications such as data acquisition systems: USB/PXI/Ethernet, instrumentation and industrial control loops, audio testing and measurement, vibration and asset condition monitoring, 3-phase power quality analysis, sonar, high precision medical electroencephalogram (EEG)/electromyography (EMG)/electrocardiogram (ECG).
