The AD8138 is a low distortion differential ADC driver with easy-to-use single-ended-to-differential conversion, adjustable output common-mode voltage, externally adjustable gain, low harmonic distortion, and other features. It can be used for ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers, and line drivers.
The AD8138 is a high‑speed differential ADC driver that can convert single‑ended signals to differential outputs or amplify differential signals. It offers adjustable common‑mode voltage, low harmonic distortion and a wide supply range.
The document includes features, pin configuration, electrical specifications, layout recommendations and example circuits for driving high‑performance ADCs such as the AD9224 and AD9203.
