MAX7451ESA+T

Video Processing Overview

The MAX7451ESA+T is a video-signal conditioner designed for standard-definition video inputs. It operates from dual ±3.3V power supplies and restores the DC level of the video input while correcting amplitude errors up to ±6dB. The device integrates an automatic gain control (AGC), loss-of-sync detector, and out-of-band noise filter. It features back-porch clamping to ground and drives a standard 150Ω video load with selectable buffer gain of 0dB or +6dB. The component is specified for operation over the extended temperature range of -40°C to +85°C.

Video Processing Feature Summary

• Integrates automatic gain control to normalize signal amplitude
• Clamps output back-porch voltage to ground
• Includes loss-of-sync detection logic output
• Features built-in out-of-band noise filtering

Video Processing Applications

• Signal conditioning for standard-definition video inputs
• Security video systems
• Video-switching systems

Video Processing Procurement Notes

Verify that the ordering suffix matches the specific package variant required for your design. Confirm the supply voltage requirements align with your system architecture before procurement. Ensure thermal management considerations are addressed for the exposed pad configuration during installation.

Video Processing Selection Notes

Select this part when dual ±3.3V supplies are available and ground-referenced video outputs are required. It is suitable for applications needing integrated AGC and noise filtering without external components. Consider alternative models if single-supply operation or adjustable clamp levels are necessary.

Video Processing Part Context

This component belongs to the MAX7450/MAX7451/MAX7452 family of video-signal conditioners. While sharing core functionality, each model differs in supply voltage and clamp capabilities. The MAX7451 specifically targets dual ±3.3V systems with fixed ground clamping.

Video Processing Replacement Considerations

MAX7450ESA requires ±5V supplies. MAX7452ESA uses a single +5V supply with adjustable clamp.
