Power Supply IC Series for TFT-LCD Panels
Gamma voltage generated IC
with built-in DAC
BD8149MUV
No.16035EBT17
Description
The feature of gamma voltage generated IC BD8149MUV provides a single-chip solution with a high-precision 10-bit DAC
setting controlled by I2C serial communications interface and a Buffer AMP (12ch). EEPROM auto-read function is also
incorporated.
Features
1) Single-chip design realizes fewer components
2) Built in 10bit DAC
3) Built in DAC output buffer amplifier (12ch)
4) Double Register synchronous switching function (SEL)
5) I2C interface (SDA, SCL)
STANDARD-MODE, FAST-MODE changeable
6) EEPROM auto-read function
7) Thermal Shut Down circuit
8) Under Voltage Lock Out circuit
9) Power ON Reset circuit
10) Input tolerant (SDA, SCL, EN, EN_AR, SEL)
11) VQFN032V5050 package
Applications
It may be used with TFT-LCD panels, such as big screen and high resolution LCD televisions.
