Product Information
Product Overview
AD7768-4 is a 4-channel 24bit, simultaneous sampling, sigma-delta (Σ-Δ) analog-to-digital converter (ADC) with power scaling and 110.8KHz bandwidth. The devices have a Σ-Δ modulator and digital filter per channel, which enables synchronized sampling of AC and DC signals. Typical applications include 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).

- 256KSPS maximum ADC ODR per channel, 108dB dynamic range, -120dB THD typical
- ±2ppm of FSR integral nonlinearity (INL), ±50µV offset error, ±30ppm of FSR gain error
- Optimized power dissipation vs. noise vs. input bandwidth
- Selectable power, speed, and input bandwidth: Fast (highest speed): 110.8KHz BW, 51.5mW/ch
- Per channel digital filter
- Programmable input bandwidth/sampling rates
- CRC error checking on data interface and daisy-chaining
- 64 lead LQFP package
- Operating temperature range from -40 to 105°C
