Frequently Asked Questions
What is the bandwidth of the BUF11704AIPWPR and why does it matter for LCD applications?
The BUF11704AIPWPR has a 3dB bandwidth of 1 MHz, which ensures fast settling of gamma reference voltages during display refresh cycles, resulting in accurate gray-level representation and minimal crosstalk between gamma channels in TFT-LCD panels.
How many channels does the BUF11704AIPWPR provide and what functions do they serve?
The BUF11704AIPWPR provides 10 buffer channels plus a VCOM driver. The 10 channels buffer the gamma voltage references required for TFT-LCD grayscale calibration, while the VCOM driver provides the common voltage needed to drive the liquid crystal layer in the panel.
What package does the BUF11704AIPWPR use and is it RoHS compliant?
The BUF11704AIPWPR is housed in a 28-pin HTSSOP package with exposed thermal pad for improved heat dissipation. It is RoHS compliant (Pbfree Code: Yes, JESD-609 Code: e4), making it suitable for lead-free manufacturing processes worldwide.
What is the maximum input offset voltage of the BUF11704AIPWPR?
The BUF11704AIPWPR has a maximum input offset voltage of 20,000 µV (20 mV). This parameter is important for gamma buffer applications because higher offset shifts the output gamma curve, potentially affecting the color accuracy and contrast ratio of the TFT-LCD panel.
