14-Channel Programmable Switchable I²C
TFT-LCD Reference Voltage Generator
with Integrated 4-Channel Static Gamma
Drivers
The ISL24006 is a 14-channel programmable switchable
reference voltage generator with four channels of static
gamma drivers integrated, for a complete 18-channel total
gamma solution for TFT-LCD displays. The 14-channel
programmable switchable configuration allows switching
between two gamma curves.
The ISL24006 is divided into two banks of seven generators:
one designed to cover the range from V_{REFL_L} to V_{REFL_H};
the remaining seven channels covering the range from
V_{REFU_L} to V_{REFU_H}. Each bank has its own separate high
and low reference inputs, with integrated buffers (four static
gamma drivers) to drive the column driver internal DAC
resistor string to within 0.2V from the top and bottom rails.
An output MUX is used to switch between the two curves in
less than 1µs. Switching is controlled using an external
select pin.
ISL24006 includes an I²C interface for programming the
offset values.
ISL24006 is available in the 38-pin QFN package and is
specified for operation over the -40°C to +85°C temperature
range.
