MAX7443ESA+T

Overview

The MAX7443ESA+T is a triple-channel video reconstruction filter and buffer designed for composite and Y/C outputs. It operates on a single +5V supply with low power consumption of 10mW per channel. The device features a precise 27MHz cutoff frequency and includes an internal reference voltage generator. It provides high-speed settling time of 6ns to 0.1% and supports a maximum output current of 50mA. The unit is housed in an 8-pin SOIC-EP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Triple-channel architecture for simultaneous signal processing
• Integrated reference voltage generator eliminates external components
• High-speed settling capability for accurate video reconstruction
• Low-power operation suitable for battery-driven applications

Applications

• Composite video signal conditioning
• Y/C (S-Video) output buffering
• Video reconstruction filtering
• Portable video equipment signal processing

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging versus the non-tape variant. Confirm RoHS compliance status through official documentation. Check for end-of-life notifications or obsolescence warnings from Analog Devices. Ensure the supplier provides valid traceability for the Maxim Integrated brand origin.

Selection Notes

Select this component when triple-channel video filtering is required in a compact surface-mount package. Consider the 27MHz bandwidth for standard definition video applications. Evaluate the single-supply operation against system power constraints. Compare the 50mA drive capability against load requirements for long cable runs.

Part Context

This part belongs to the MAX7443 family of video filters. It serves as a specialized interface filter for analog video signals. The device integrates multiple functions into a single chip to reduce board space. It is distinct from general-purpose operational amplifiers due to its optimized video performance characteristics.

Replacement Considerations

Public confirmed substitutes include the MAX7444ESA+T for quad-channel requirements. Verify pin compatibility before substitution. Check datasheet differences for bandwidth and drive current variations.
