DS3510T+

Overview

The DS3510T+ is an I2C-compatible gamma and VCOM buffer with EEPROM, manufactured by Analog Devices Inc./Maxim Integrated. It features ten 8-bit gamma buffers and one 8-bit VCOM buffer, each supported by four bytes of non-volatile EEPROM memory. The device operates with a digital supply voltage ranging from 2.7V to 5.5V and an analog supply voltage between 9.0V and 15.0V. It supports I2C clock frequencies up to 400kHz and includes flexible control via hardware pins or software registers. The component is housed in a 48-pin TQFN package with an exposed pad.

Feature Summary

• Integrates high-performance rail-to-rail buffer amplifiers for low-power gamma channels and a high-current drive VCOM channel optimized for TFT-LCD panels.
• Provides multibyte storage capability through on-chip EEPROM, enabling the retention of gamma and VCOM data across power cycles.
• Supports multiple operating modes including banked updates controlled by hardware pins or software bits, as well as individual channel control via I2C.
• Features dual independent data registers per channel to enhance interface performance and allow asynchronous updates.

Applications

• TFT-LCD Gamma and VCOM Buffer
• Adaptive Gamma and VCOM Adjustment
• Industrial Process Control

Procurement Notes

Verify the specific ordering suffix to confirm the packaging type, such as tape and reel versus tube. Ensure the temperature range matches the application requirements, as the DS3510T+ variant covers -45°C to +95°C. Confirm lead-free status and RoHS compliance based on the manufacturer's current documentation before finalizing procurement.

Selection Notes

Select this component when designing systems requiring precise gamma correction and VCOM generation for TFT-LCD displays. Consider the need for non-volatile data storage and the flexibility of I2C versus pin-controlled bank selection. Evaluate the power supply constraints to ensure compatibility with the specified 2.7V to 5.5V digital and 9.0V to 15.0V analog supply ranges.

Part Context

The DS3510 belongs to the Maxim Integrated family of LCD gamma buffers. It is designed to replace discrete resistor networks and operational amplifiers typically used for gamma generation. The device simplifies board layout by integrating DACs, buffers, and memory into a single compact package, reducing component count and design complexity for display drivers.
