Power Supply IC Series for TFT-LCD Panels
High-precision
Gamma Correction ICs with built-in DAC
BD8132FV, BD8139AEFV
No.09035EBT02
●Description
These gamma correction voltage generation ICs feature built-in DACs and provide a single-chip solution with setting control
via serial communications, a high-precision 10-bit DAC, an output amp (18-channel or 10-channel), and Vcom.
●Features
1) Single-chip design means fewer components
2) Built-in 10 bit DAC (18ch: BD8132FV, 10ch: BD8139AEFV)
3) Built-in DAC output amp
4) Built-in Vcom amp
5) Built-in auto-read function
6) 3-line serial interface (BD8132FV) or 2-wire serial (BD8139AEFV)
7) Thermal shutdown circuit
8) SSOP-B40 package (BD8132FV) / HTSSOP-B40 package (BD8139AEFV)
●Applications
These ICs can be used with TFT LCD panels used by large-screen and high-definition LCD TVs.
●Absolute maximum ratings (Ta = 25°C)
