AD8138AARMZ-R7

Overview

The AD8138AARMZ-R7 is a low distortion differential amplifier manufactured by Analog Devices Inc. It features a 320 MHz bandwidth and 1150 V/µs slew rate. The device operates on supply voltages from 2.7 V to ±5.5 V with a typical quiescent current of 20 mA. It provides a 1 mV offset voltage and 95 mA output current capability. The component is housed in an 8-lead MSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

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

Applications

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