AD7387-4 Description
The single-ended analog input accepts voltage from 0 V to VREF, and is sampled and converted on the falling edge of CS. The AD7386-4/AD7387-4/AD7388-4 have on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling can boost up to two bits of added resolution.
