BUF07703PWP

Video Amps And Modules Overview

The BUF07703 is a multi-channel LCD gamma correction buffer featuring six dedicated gamma channels and one integrated VCOM buffer. It operates within a supply voltage range of 4.5V to 16V and supports an operating temperature range from -40°C to +85°C. The device utilizes a TSSOP-20 PowerPAD package for enhanced thermal dissipation. Key electrical characteristics include a maximum input offset voltage of 15mV, a typical supply current of 2mA, and a slew rate of 1V/ms for the gamma channels.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to ensure correct packaging and tape-and-reel specifications. Confirm that the HTSSOP-20 PowerPAD thermal requirements align with the target PCB layout copper area for adequate heat dissipation during operation.

Video Amps And Modules Selection Notes

Select this component when six distinct gamma reference voltages are required alongside a common voltage driver. The integrated VCOM channel simplifies designs by eliminating the need for a separate high-current buffer. Ensure the application benefits from the flow-through pinout architecture which facilitates driving large capacitive loads inherent in LCD source drivers.

Video Amps And Modules Part Context

This device belongs to the BUFxx703 series, which includes variants with different channel counts such as the BUF06703 and BUF05703. The series is designed to offer flexibility in channel configuration while maintaining consistent performance characteristics across the family. It serves as a specialized solution for LCD panel interface circuits where precise voltage buffering is critical.

Video Amps And Modules Replacement Considerations

Official substitutes within the same functional family include the BUF06703 and BUF05703. These alternatives provide fewer gamma channels but retain the integrated VCOM buffer and similar electrical characteristics. Verify pin compatibility and thermal requirements when substituting between these specific models.

Video Amps And Modules FAQ

How does the input stage architecture affect buffer selection?

Buffers 1 through 3 have input stages including VDD, while buffers 4 through 6 have single PMOS input stages including GND. Buffer 1 must connect to the gamma voltage closest to VDD, and Buffer 6 to the voltage closest to GND.

What is the maximum capacitive load the device can drive?

The gamma buffers are designed to drive capacitances in excess of 100pF while retaining effective phase margins above 50 degrees. The VCOM buffer can handle even larger capacitive loads due to its higher current drive capability.

Can multiple devices be used to create more than ten gamma channels?

Yes, two or more BUFxx703 devices can be used in parallel to create configurations with more than ten gamma channels, such as 12, 14, or 18 channels, providing a cost-effective alternative to using multiple op-amps.
