AD8138ARZ-R7

The AD8138ARZ-R7 is a differential ADC driver in an 8-lead SOIC package with 320 MHz bandwidth, specified over -40 C to +85 C and supplied on a 13-inch reel; Analog Devices lists this ordering code as ACTIVE in the datasheet ordering guide. It converts a single-ended input into a balanced differential output matched to high-speed ADC inputs, preserving dynamic range and rejecting common-mode noise in the signal chain. Driving the converter directly from this stage removes the transformer or extra op amp stage many designs otherwise need, which shortens the analogue front end and improves repeatability across production units. Selection advice: use the ARZ-R7 code for the SOIC-8 package on reel; verify your ADC input common-mode range against the driver output swing in the datasheet before layout, and state reel quantity requirements in your RFQ. Parameters verified against Analog Devices documentation.
