Replacement verdict
Compatible functional replacement candidate
The AD8138ARZ and AD8131AR are both high-speed differential amplifiers in an 8-lead SOIC package, but they are not identical drop-in substitutes. The AD8138ARZ is a fully differential ADC driver with externally settable gain and a wider supply range, while the AD8131AR is a fixed-gain (×2) differential line driver with an internal gain-setting network. Designers should confirm gain configuration, supply voltage, and output swing requirements before substituting one for the other.
