AD8275 is a G = 0.2, 16-Bit ADC Driver from Analog Devices. The product can translate ±10 V to +4 V and drive 16-bit SAR ADCs. AD8275 features a small MSOP package, input overvoltage protection, fast settling time, rail-to-rail output, and high CMRR. The product can be used for level translation, ADC driver, instrumentation amplifier building block, and automated test equipment applications.
The AD8275 is a G = 0.2 difference amplifier designed to translate +10 V signals to a +4 V level for 16‑bit SAR ADCs. It offers rail‑to‑rail output, a small 8‑lead MSOP package, and input over‑voltage protection from +40 V to –35 V, making it suitable for industrial and instrumentation data‑acquisition systems.
Key specifications include an operating supply range of 3.3 V to 15 V, low gain drift of 1 ppm/°C, high CMRR of 80 dB, and a fast 0.001 % settling time of 450 ns. The document provides pin descriptions, typical application circuits, performance graphs, and an ordering guide for various package options.
