The AD7608 is an 8-channel data acquisition system with 18-bit, bipolar, simultaneous sampling ADC, which can be applied to power line monitoring and protection systems, multiphase motor control systems and other fields
The AD7608 provides eight simultaneously sampled analog inputs with true bipolar ranges of +10 V and +5 V. It operates from a single 5 V supply, includes on‑chip reference and buffer, and features a second‑order antialiasing filter and input clamp protection. The device delivers up to 200 kSPS on all channels and offers flexible parallel or serial (SPI/QSPI/MICROWIRE) interfaces.
Typical applications include power‑line monitoring, motor control, instrumentation, multi‑axis positioning, and general data‑acquisition systems. The datasheet also lists companion products such as reference regulators and digital isolators, and provides detailed timing, pin‑out, and layout guidelines for system designers.
| Resolution | 18 Bits |
|---|---|
| Signal‑to‑Noise Ratio (typical, no oversampling, +10 V range) | 89.5 dB |
| Throughput Rate (per channel) | 200 kSPS |
| Input Impedance | 1 MΩ |
| Supply Voltage | Single 5 V supply |
The AD7608 supports true bipolar analog input ranges of +10 V and +5 V.
In standby mode the device draws about 5 mA.
The AD7608 is offered in a 64‑lead low‑profile quad flat package (LQFP).
The typical SNR without oversampling at a +10 V range is 89.5 dB.
