The AD7768 is an 8-channel and 4-channel, simultaneous sampling sigma-delta (Σ-Δ) analogue-to-digital converters (ADCs), respectively, with a  (Σ-Δ)modulator and digital filter per channel, enabling synchronized sampling of ac and dc signals.
The AD7768 achieves 108 dB dynamic range at a maximum input bandwidth of 110.8 kHz, combined with typical performance of ±2 ppm INL, ±50 µV offset error, and ±30 ppm gain error.
The AD7768 user can trade off input bandwidth, the 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 AD7768 allows them to become reusable platforms for low power dc and high-performance ac measurement modules.
The AD7768 has three modes: fast mode (256 kSPS maximum, 110.8 kHz input bandwidth, 51.5 mW per channel), median mode (128 kSPS maximum, 55.4 kHz input bandwidth, 27.5 mW per channel) and eco mode (32 kSPS maximum, 13.8 kHz input bandwidth, 9.375 mW per channel).
