8-/4-Channel, 24-Bit, Simultaneous Sampling adcs with Power Scaling, kHz BW. Data Sheet AD7768/AD7768-4. FEATURES Linear phase digital filter Precision ac and dc performance Low latency sinc5 filter 8-/4-channel Simultaneous Sampling Wideband brick wall filter: dB ripple to kHz 256 kSPS maximum ADC ODR per channel Analog input precharge buffers 108 dB dynamic range Power supply kHz maximum input bandwidth ( 3 dB BW) AVDD1 = V, AVDD2 = V to V. 120 dB THD, typical IOVDD = V to V or IOVDD = V. 2 ppm of full-scale range (FSR) integral nonlinearity 64-lead LQFP package, no exposed pad (INL), 50 V offset error, 30 ppm gain error Temperature range: 40 C to +105 C. Optimized power dissipation vs.
converters (ADCs), respectively, with a Σ-Δ modulator and digital filter per channel, enabling synchronized sampling of ac and dc signals. The AD7768/AD7768-4 achieve 108 dB dynamic range at a maximum input bandwidth of 110.8 kHz, combined with typical performance of ±2 ppm integral nonlinearity (INL), ±50 μV
