BUF04701AIPW

Overview

The BUF04701AIPW is a quad buffer amplifier manufactured by Texas Instruments, designed for high-performance video and LCD gamma correction applications. It operates on a single supply voltage ranging from 3.5 V to 12 V. The device features four independent channels with rail-to-rail output capability, ensuring maximum dynamic range in signal processing tasks. Packaged in a 14-TSSOP format, it supports an operating temperature range of -40°C to 125°C. The component exhibits an -3dB bandwidth of 8 MHz, suitable for driving capacitive loads typical in TFT-LCD panels.

Feature Summary

• Four-channel configuration providing independent signal buffering capabilities
• Rail-to-rail output stage for optimized signal swing
• Single-supply operation compatible with low-voltage systems
• Designed specifically for LCD gamma buffer and video amplifier applications

Applications

• TFT-LCD panel gamma correction circuits
• Video signal buffering and conditioning
• CMOS buffer amplifier stages in display drivers

Procurement Notes

Verify the specific suffix (e.g., IPW vs IPR) to confirm packaging type, as the base part number may refer to bulk or reel variants. Confirm the active status, as some listings indicate obsolete lifecycle stages. Ensure the 14-TSSOP package matches your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Validate the supply voltage range against your system design constraints before procurement.

Selection Notes

Select this component when a quad buffer with rail-to-rail output is required for LCD gamma generation. Consider the 8 MHz bandwidth limit for high-speed video signals. Evaluate the 14-TSSOP package size against available board space. Compare power consumption at the intended supply voltage against other quad buffers. Ensure the -40°C to 125°C temperature range meets environmental specifications.

Part Context

This device belongs to Texas Instruments' family of CMOS buffer amplifiers tailored for display applications. It serves as a dedicated solution for generating precise voltage levels needed for LCD gamma correction. The quad architecture reduces component count compared to using discrete single-channel buffers. It complements other Texas Instruments video and display driver ICs in complete panel driving solutions.

Replacement Considerations
