MAX9668 10位可编程gamma基准系统，为TFT L
max9668 10位可编程gamma基准系统，为tft lcd提供mtp
概述
the max9668 outputs eight voltage references for gamma correction in tft lcds and one voltage reference for vcom. each gamma reference voltage has its own 10-bit digital-to-analog converter (dac) and buffer to ensure a stable voltage. the vcom reference voltage has its own 10-bit dac and an amplifier to ensure a stable voltage when critical levels and patterns are displayed. the max9668 features integrated multiple-time programmable (mtp) memory to store gamma and vcom values on the chip, eliminating the need for external eeprom. the max9668 supports up to 100 write operations to the on-chip nonvolatile memory.
the gamma outputs can drive 250ma peak transient current and settle within 1μs. the vcom output can provide 400ma 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.
关键特性
8-channel gamma correction 10-bit resolution
vcom driver
integrated mtp memory
programmable vcom limits
1µs settling time
20v maximum analog supply voltage
250ma peak current on gamma channels
