18-Channel Programmable I C TFT-LCD Reference Voltage Generator with Integrated

Calibrator and 2 Banks of EEPROM

COM

The ISL24833 is an 18-channel, 10-bit I C programmable

Features

reference voltage generator for TFT-LCDs with dual bank outputs.

It also provides an I C programmable, 1-channel, 8-bit V

• 18-channel I C programmable 10-bit DACs

COM

calibrator with a V

amplifier and internal EEPROM.

• Integrated I C programmable 8-bit V

calibrator

COM

The two output banks are capable of switching quickly (<1µs)

enabling rapid switching between two gamma curves (or

operational modes) in TFT-LCD applications. The ISL24833

also integrates two banks of EEPROM that can store all

reference voltage data. The EEPROM is capable of >300 write

cycles.

• One V op amp

COM

• Two banks of EEPROM storage (rewritable >300 times)

• Fast output bank switching: <1µs typical

• Analog supply: 12V to 18V at 15mA (unloaded)

• Digital supply: 2.5V to 3.3V at 1.3mA (unloaded)

Combining gamma and V

COM

reference voltage generators

• I C serial interface

with low power operation and EEPROM, the ISL24833 provides

a complete reference voltage solution ideal for large area

TFT-LCD display applications.

• Pb-free (RoHS compliant)

Applications

• TFT-LCD column driver reference generator

The ISL24833 is available in a 32 Ld 5mmx6mm QFN

thermally enhanced package. It is specified for operation

across the -40°C to +85°C temperature range.

• TFT-LCD V calibrator and driver

• General-purpose reference voltage generators
