Product Description
The WFP6131AGSR is an 11-channel buffer ampli-
fier that provides a
single-chip solution
to the ref-
erence voltage requirements of TFT-LCD drivers. It
can also be used in any
cost sensitive
application
that requires large number (11 maximum) of high
drive buffers in a space saving TSSOP package.
The WFP6131AGSR has two selectable inputs per
buffer allowing the selection of two reference volt-
ages via one on-chip multiplexer for all 11 buffers.
The WFP6131AGSR supports 9 or 11 reference
voltage systems. For 9 reference applications, the 2
unused amplifiers may be disabled to reduce power
dissipation.
