MAX4447ESE+T

Video Amps And Modules Overview

The MAX4447ESE+T is a single-ended-to-differential line driver designed for high-speed communications. It features a fixed gain of +2V/V and a small-signal bandwidth of 430MHz. The device delivers full-power bandwidths up to 405MHz with slew rates as high as 6500V/µs. It operates from ±4.5V to ±5.5V supplies, providing differential output swings of ±6.2V into a 50Ω load. A low-power enable mode reduces current consumption below 5.5mA.

Video Amps And Modules Feature Summary

• Converts single-ended signals to differential outputs using current feedback architecture for enhanced bandwidth.
• Includes an active-high, TTL-compatible enable input that places outputs in a high-impedance state during low-power operation.
• Features internal trimming to minimize gain errors and ensure excellent differential gain and phase characteristics.

Video Amps And Modules Applications

• High-speed differential transmitters
• Coaxial to twisted-pair converters
• xDSL applications
• Video and RF signal processing

Video Amps And Modules Procurement Notes

Verify the specific suffix '+T' indicates reel packaging when sourcing. Confirm the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the component matches the 16-pin narrow SOIC package dimensions. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity.

Video Amps And Modules Selection Notes

Select this component when a fixed +2V/V gain is required for single-ended to differential conversion. It is suitable for designs needing high slew rates and wide bandwidth without external gain-setting resistors. Consider the low-power enable feature if power management during idle states is necessary for the system.

Video Amps And Modules Part Context

This device belongs to the MAX4447/MAX4448/MAX4449 family of wideband line drivers. While the MAX4448 and MAX4449 offer variable gain configurations via external resistors, the MAX4447 provides a fixed internal gain. All variants share similar high-speed performance characteristics and pinouts within the 16-pin narrow SOIC package.

Video Amps And Modules FAQ

How does the enable pin function?

The EN pin is an active-high, TTL-compatible input. Connecting it to VCC enables normal operation, while connecting it to GND activates low-power mode, reducing supply current and placing outputs in a high-impedance state.

What is the maximum output drive current?

The device can deliver an output current drive of up to 130mA, allowing it to drive loads such as 50Ω cables effectively.
