The AD7609 is an 8-channel differential DAS with an 18-bit, bipolar, simultaneous sampling ADC. It features 8 simultaneously sampled inputs, true differential inputs, true bipolar analog input ranges, a single 5V analog supply, and a VDRIVE ranging from 2.3V to 5.25V. The product also includes a fully integrated data acquisition solution, analog input clamp protection, an input buffer with a 1MΩ analog input impedance, a second-order antialiasing analog filter, an on-chip accurate reference and reference buffer, an 18-bit ADC with 200kSPS on all channels, and oversampling capability with a digital filter.
The AD7609 is an 18‑bit, 8‑channel true differential simultaneous‑sampling analog‑to‑digital converter. It operates from a single 5 V supply and accepts +10 V or +5 V bipolar differential inputs while delivering up to 200 kSPS on all channels. Integrated features include input‑clamp protection, a second‑order antialiasing filter, on‑chip reference, and both parallel and serial digital interfaces.
The device offers low power consumption (≈100 mW in normal operation) and high input impedance (1 MΩ). It is suited for power‑line monitoring, motor control, instrumentation, positioning systems, and general data‑acquisition applications.
