Part Number: BUF16821
Function: Programmable Gamma-Voltage Generator and VCOM Calibrator / HTSSOP-28 Package
Manufacturer: Texas Instruments
The BUF16821 offers 16 programmable gamma channels and two programmable V COM channels.
The final gamma and V COM values can be stored in the on-chip, nonvolatile memory. To allow for programming errors or liquid crystal display (LCD) panel rework, the IC supports up to 16 write operations to the on-chip memory.
The BUF16821 has two separate memory banks, allowing simultaneous storage of two different gamma curves to facilitate switching between gamma curves.
