The ADAS3022 is a 16‑bit, 1 MSPS, 8‑channel data acquisition system with programmable gain, internal 4.096 V reference and ±24.576 V input range.
The ADAS3022 is a complete data‑acquisition system that integrates an 8‑channel low‑leakage multiplexer, a high‑impedance programmable‑gain instrumentation amplifier (PGIA), a precision 4.096 V reference, and a 16‑bit SAR ADC. It operates from a ±15 V supply and supports differential or single‑ended inputs up to ±24.576 V.
Designed for industrial and instrumentation applications, the device offers up to 1 MSPS conversion rate, 500 MΩ input impedance, and a temperature range of –40 °C to +85 °C. It is available in a 6 mm × 6 mm LFCSP package and includes extensive digital interfaces (SPI/SPORT) for easy integration. This manual is written in Chinese.
