AD8138SRMZ-EP-R7

Overview

The AD8138SRMZ-EP-R7 is a low distortion differential ADC driver manufactured by Analog Devices Inc. It features a -3 dB bandwidth of 320 MHz at G = +1 and a slew rate of 1150 V/μs. The device operates within an extended temperature range of -55°C to +105°C and supports supply voltages from ±1.4 V to ±5.5 V. It delivers a quiescent current of 20 mA and dissipates maximum power of 550 mW. The component utilizes an 8-lead MSOP package with a tape and reel configuration.

Feature Summary

• Supports defense and aerospace applications through controlled manufacturing baselines and enhanced product change notification protocols.
• Features unique internal feedback that provides balanced output gain and phase matching while suppressing even-order harmonics.
• Offers adjustable output common-mode voltage via the VOCM pin for easy level-shifting in single-supply systems.

Applications

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

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the 7-inch tape and reel packaging format as documented in the official Analog Devices AD8138-EP datasheet. Confirm that the EP designation ensures compliance with the extended temperature range and controlled manufacturing baseline requirements necessary for qualified defense and aerospace deployments.

Selection Notes

Select this component when operation within the -55°C to +105°C temperature range is required, distinguishing it from standard industrial variants. Ensure the design accommodates the 8-lead MSOP package dimensions and thermal characteristics. Verify that the supply voltage constraints between ±1.4 V and ±5.5 V align with the system power architecture.

Part Context

This part belongs to the AD8138-EP series, representing the enhanced product variant of the AD8138 family. It is specifically engineered for high-reliability environments requiring strict quality control. The SRMZ suffix indicates the specific MSOP package style combined with RoHS compliance and the reel packaging option.

Replacement Considerations

Standard AD8138 variants lack the extended temperature range and controlled manufacturing baseline. Direct substitution requires verifying if the application demands the specific AQEC qualifications provided by the EP series.
