EL5123, EL5223, EL5323, EL5423
12MHz 4-, 8-, 10- and 12-Channel Rail-to-Rail Input-Output Buffers
The EL5123, EL5223, EL5323, and EL5423 are low power,
high voltage rail-to-rail input/output buffers designed
primarily for use in reference voltage buffering applications
for TFT-LCDs. They are available in quad (EL5123), octal
(EL5223), 10-Channel (EL5323), and 12-Channel (EL5423)
topologies. All buffers feature a -3dB bandwidth of 12MHz
and operate from just 600µA per buffer. This family also
features fast slewing and settling times, as well as a
continuous output drive capability of 30mA (sink and
source).
The quad channel EL5123 is available in the 10 Ld MSOP
package. The 8-Channel EL5223 is available in both the
20 Ld TSSOP and 24 Ld QFN packages, the 10-Channel
EL5323 in the 24 Ld TSSOP and 24 Ld QFN packages, and
the 12-Channel EL5423 in the 28 Ld TSSOP and 32 Ld QFN
packages. All buffers are specified for operation over the full
-40°C to +85°C temperature range.
Features
• 12MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) = 600µA
• High slew rate = 15V/µs
• Rail-to-rail input/output swing
• Ultra-small packages
• Pb-Free Available (RoHS Compliant)
Applications
• TFT-LCD drive circuits
• Electronics notebooks
• Electronic games
• Touch-screen displays
• Personal communication devices
• Personal digital assistants (PDA)
• Portable instrumentation
• Sampling ADC amplifiers
• Wireless LANs
• Office automation
• Active filters
• ADC/DAC buffers
