MAX7432EUD+T

Overview

The MAX7432EUD+T is a standard definition video reconstruction filter and buffer manufactured by Analog Devices Inc./Maxim Integrated. It features a sixth-order low-pass filter designed for NTSC, PAL, and SDTV signals. The device operates on a single +5V supply and utilizes the Maxim Single-Pin Bus (MSPB) interface for digital control of channel selection, high-frequency boost, bypassing, and output disable. It is housed in a 14-pin TSSOP package.

Feature Summary

• Integrates a sixth-order low-pass filter optimized for standard definition video signal reconstruction
• Supports digital configuration via the Maxim Single-Pin Bus interface for input selection and boost control
• Capable of driving dual 150-ohm video loads with rail-to-rail output capability

Applications

• Standard Definition Video Reconstruction
• Anti-aliasing and DAC smoothing for composite video
• Set-top boxes and DVD players
• Camcorders and hard-disk recorders

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing from distributors. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure component authenticity. Cross-reference the 14-pin TSSOP physical dimensions against your PCB footprint requirements prior to finalizing procurement orders.

Selection Notes

Select this component for applications requiring integrated filtering and buffering for NTSC, PAL, or SDTV signals without discrete components. Ensure the system provides a stable +5V single supply. Verify that the MSPB interface logic levels are compatible with the controlling microcontroller or processor used in the design architecture.

Part Context

This part belongs to the MAX7428/MAX7430/MAX7432 family of video filters. While the MAX7428 offers a single channel in an SOT23 package and the MAX7430 provides dual channels in a µMAX package, the MAX7432EUD+T specifically provides dual-channel functionality in a 14-pin TSSOP package suitable for higher pin-count designs.

Replacement Considerations

Public confirmed substitute part numbers include MAX7432AEUD+T within the same product family.
