AD7608 is an 8-channel data acquisition chip launched by Analog Devices. It has 18-bit, bipolar, simultaneous sampling ADC, and has a 7 kV ESD rating and 98 dB SNR performance. The chip is widely used in power line monitoring and protection systems, multiphase motor control, instrumentation and measurement, and power electronics.
The AD7608 is an 18‑bit, 8‑channel simultaneous‑sampling analog‑to‑digital converter that operates from a single 5 V supply and supports true bipolar input ranges of +10 V and +5 V. It includes on‑chip reference, input clamp protection, a second‑order antialiasing filter, and flexible parallel/serial interfaces.
The handbook provides a functional block diagram, detailed specifications, timing diagrams, layout recommendations, and ordering information for the 64‑lead LQFP package, making it a comprehensive reference for designers integrating the AD7608 into data‑acquisition systems.
| Resolution | 18 Bits |
