AD8138ARMZ-REEL7

Overview

The AD8138ARMZ-REEL7 is a low distortion differential ADC driver manufactured by Analog Devices Inc. It features a 320 MHz gain bandwidth product and an 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, 6 MΩ differential input resistance, and 95 mA output current capability. It provides -94 dBc second harmonic distortion at 5 MHz and settles to 0.01% in 16 ns.

Feature Summary

• Internal common-mode feedback loop ensures balanced output gain and phase matching while suppressing even-order harmonics.
• Adjustable output common-mode voltage via the VOCM pin allows easy level-shifting for driving single-supply ADCs.
• High-speed signal processing capabilities including fast overdrive recovery and wide bandwidth suitable for high-frequency applications.

Applications

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

Procurement Notes

Verify the specific REEL7 suffix indicates tape-and-reel packaging when sourcing. Confirm the MSOP-8 package variant matches the design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the system environment. Cross-reference the manufacturer part number AD8138ARMZ-REEL7 with official Analog Devices documentation to validate specifications.

Selection Notes

Select this component for applications requiring precise differential signaling with minimal harmonic distortion. The adjustable VOCM pin simplifies interface design for varying ADC reference levels. Consider the 95 mA output drive capability for loading requirements. Evaluate the thermal performance within the MSOP-8 package constraints for power dissipation limits.
