AD8275 is a 16-bit SAR ADC driver with an input range of ±10 V to +4 V, a 5 V supply voltage, a 2.5 μV low offset drift, and a 1 ppm/°C low gain drift.
The AD8275 is a G = 0.2 difference amplifier designed to translate +10 V signals to a +4 V level for single‑supply ADCs. It provides rail‑to‑rail output, wide supply operation (3.3 V to 15 V) and low gain drift, making it suitable for data‑acquisition and instrumentation applications.
Key features include fast 450 ns settling time, high CMRR (80 dB), low offset drift (2.5 pV/°C), and an 8‑lead MSOP package. The datasheet supplies detailed specifications, pin configuration, typical application circuits, and ordering information.
