AD8138ARMZ-REEL

Overview

The AD8138ARMZ-REEL is a low distortion differential ADC driver manufactured by Analog Devices Inc. in an 8-lead MSOP package. It features a 320 MHz small signal bandwidth and a 1150 V/µs slew rate. The device operates on supply voltages ranging from +3 V to ±5 V with a typical quiescent current of 20 mA. Key electrical parameters include a 1 mV typical offset voltage, 5 nV/√Hz input voltage noise, and 95 mA output current capability.

Feature Summary

• Provides easy single-ended-to-differential conversion with adjustable output common-mode voltage via the VOCM pin.
• Features externally adjustable gain and internal feedback for balanced output gain and phase matching.
• Delivers low harmonic distortion performance suitable for driving high-speed analog-to-digital converters.

Applications

• ADC drivers
• Single-ended-to-differential converters
• IF and baseband gain blocks
• Differential buffers
• Line drivers

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Cross-reference the 8-lead MSOP footprint dimensions during PCB layout validation.

Selection Notes

Select this component for applications requiring high bandwidth and low distortion in differential signal processing. Consider the 320 MHz bandwidth and fast settling time for high-frequency data acquisition systems. Evaluate the power consumption at 90 mW for battery-operated or thermally constrained designs.

Part Context

This part belongs to the AD8138 series of differential amplifiers designed for simplified differential signal amplification. Manufactured on Analog Devices' proprietary XFCB bipolar process, it offers superior harmonic distortion suppression compared to standard operational amplifier configurations used for similar tasks.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers within the same product family or equivalent performance tiers before implementation.
