BUF08630RGWR Description

Short technical summary and product information.

The BUF08630RGWR from Texas Instruments is an 8-channel gamma-voltage generator with an additional programmable VCOM channel, designed for TFT-LCD reference drivers. It offers 10-bit resolution across its eight gamma channels and one VCOM channel, allowing for precise control of display characteristics.

This device operates with a supply voltage ranging from 9V to 20V and a digital supply voltage from 2V to 5.5V. It features an I2C interface supporting speeds of 400 kHz and 3.4 MHz, enabling efficient communication. The gamma and VCOM values can be stored in the on-chip, 16x rewritable nonvolatile memory, providing flexibility for programming and error correction.

Key electrical specifications include a high slew rate for VCOM at 45 V/µs and rail-to-rail output capability with a minimum swing of 300 mV. The maximum output current is greater than 300 mA. The BUF08630RGWR is housed in a 25 mm² VQFN package and operates within an environmental temperature range of -40°C to 95°C.

Applications for this gamma-voltage generator include TFT-LCD reference drivers for displays ranging from 7 inches to 21 inches and above. Its features make it suitable for various display applications requiring accurate gamma and VCOM voltage generation.
