FEATURES
Complete suite of level shifters
Eight inverting and three complementary level shifters for
LCD timing
High voltage edge detector
Integrated low offset buffer for VCOM drives high capacitive
loads
MUXed input, low offset buffer for 2-level precharge drives
high capacitive loads
High current buffer for precharge provides high current
drive into large capacitive loads
Low power dissipation: 576 mW
Available in 48-lead 7 mm × 7 mm LFCSP E-pad
PRODUCT DESCRIPTION
The ADSY8401 provides fast, 3 V to 15 V level shifters for LCD
panel timing signals. An integrated low offset analog buffer is
capable of driving the high capacitive loads. A 2:1 MUX input,
low offset buffer simplifies application of 2-level precharge
signals. A high current buffer provides high slew rates for large
capacitive loads.
The ADSY8401 is fabricated on ADI’s fast, 26 V XFHV process,
providing fast input logic, high voltage level shifters, and
precision drive amplifiers on the same chip.
The ADSY8401 dissipates 576 mW nominal static power.
The ADSY8401 is offered in a 48-lead 7 mm × 7 mm LFCSP
E-pad package and operates over the commercial temperature
range of 0°C to 85°C.
