AD8138ARM-REEL

Overview

The AD8138ARM-REEL is a low distortion differential ADC driver manufactured by Analog Devices Inc. in an 8-lead MSOP package. It features a -3 dB bandwidth of 320 MHz at G = +1 and a slew rate of 1150 V/µs. The device settles to 0.01% in 16 ns with an overdrive recovery time of 4 ns. Input voltage noise is 5 nV/√Hz, and typical offset voltage is 1 mV. Operating supply range is +3 V to ±5 V with quiescent current of 20 mA.

Feature Summary

• Internal feedback architecture provides balanced output gain and phase matching while suppressing even-order harmonics.
• Adjustable output common-mode voltage via the VOCM pin enables easy level-shifting for single-supply ADC driving.
• Externally adjustable gain minimizes errors associated with external resistor mismatches.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type and reel configuration. Confirm that the component meets RoHS compliance standards for your region. Ensure the supply voltage requirements align with your system design before procurement.

Selection Notes

Select this component when high linearity and low harmonic distortion are critical for driving high-speed data converters. The wide supply range supports both single and dual supply architectures. Consider the MSOP package for space-constrained PCB layouts requiring surface mount technology.

Part Context

This part belongs to the AD8138 family of differential amplifiers designed for signal processing applications. It utilizes Analog Devices' proprietary XFCB bipolar process to achieve high performance with low power consumption. The device simplifies differential signal amplification compared to traditional op-amp configurations.

Replacement Considerations

Direct substitutes include other parts within the AD8138 series such as the AD8138ARZ or AD8138AARMZ variants, provided they match the required package and electrical specifications.
