The AD8270 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier with gains of 0.5, 1, or 2. Single ended amplifiers have over 40 different gain settings and allow the reference voltage to be set at midsupply.
The AD8270 is a low‑distortion, dual‑channel precision difference amplifier with internal gain‑setting resistors. It can be configured for difference‑amplifier gains of 0.5, 1, or 2, or for over 40 single‑ended gain options ranging from –2 to +3. The device operates from a 2.5 V to +18 V supply, draws only 2.5 mA per channel, and is specified for –40 °C to +85 °C operation.
The datasheet provides full specifications, absolute maximum ratings, pin‑out diagrams, typical performance curves, and ordering information for the 16‑lead LFCSP package. It also includes application notes such as driving ADCs, cabling considerations, and power‑supply recommendations.
