High-precision Gamma Correction ICs with built-in DAC

ROHM is developing ICs that generate graded voltage for simple digital control and highly precise adjustment of the voltage gamma in large-format, high-definition displays. A maximum of 18 channels of gamma output are available, making them ideal for full HD panels that require fine adjustment capabilities.

Features

High voltage error accuracy (±0.1%) compatible with the gamma settings of high-definition full HD displays

ROHM's high-precision gamma voltage generating ICs with built-in DAC feature a high voltage error accuracy of ±0.1% - unattainable using conventional externally attached resistors - making it possible to precisely set the gamma correction of HD LCD TVs.

Digital gamma settings without the need to change the circuit board - ever
Automatic data reading function built in (AUTO READ) (BD8132FV, BD8139AEFV)
Two types of interfaces are available: 3-wire and I2C BUS (3wire : BD8132FV, BD8143MUV I2C BUS : BD8139AEFV)
Built-in parity function (error detection) that rejects errors caused by noise (BD8139AEFV)
