BUF16821AIPWPR Description

Short technical summary and product information.

The BUF16821AIPWPR from Texas Instruments is an active 16-channel gamma-voltage generator and Vcom calibrator designed for LCD displays. It integrates a gamma buffer and VCOM functionality, supporting an I2C interface with speeds up to 3.4MHz.

This device operates with a supply voltage ranging from 9V to 20V and a digital supply voltage from 2V to 5.5V. It offers 10-bit resolution across its 16 programmable gamma channels and 2 programmable VCOM channels. The final gamma and VCOM values can be stored in on-chip, nonvolatile memory, with two independent pin-selectable memory banks available.

The BUF16821AIPWPR is housed in a 28-pin HTSSOP package with dimensions of 9.7 mm x 6.4 mm. It features rail-to-rail output with a minimum swing of 300mV at 10mA and a maximum output current exceeding 300mA. The operating temperature range is from -40°C to 85°C.

Applications for this component include TFT-LCD reference drivers for displays ranging from 7 inches to 21 inches and above. It is suitable for source driver voltage requirements between 9V and 20V.
