- DAC Reference Input
- 12/14/16-Channel Gamma Correction, 10-Bit Resolution
- VCOM Driver
- Integrated MTP Memory
- Programmable VCOM Limits
- 200mA Peak Current on Gamma Channels
- 600mA Peak Current on VCOM Channel
- TFT LCDs
The gamma outputs can drive 200mA peak transient current and settle within 1µs. The VCOM output can provide 600mA peak transient current and also settles within 1µs. The analog supply voltage range extends from 9V to 20V, and the digital supply voltage range extends from 2.7V to 3.6V.
Gamma values and the VCOM value are programmed into registers through the I²C interface.
