EL5221C
Dual 12MHz Rail-to-Rail Input-Output Buffer
Features
General Description
• 12MHz -3dB bandwidth
• Unity gain buffer
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) =
500µA
The EL5221C is a dual, low power, high voltage rail-to-rail input-out-
put buffer. Operating on supplies ranging from 5V to 15V, while
consuming only 500µA per channel, the EL5221C has a bandwidth of
12MHz (-3dB). The EL5221C also provides rail-to-rail input and out-
put ability, giving the maximum dynamic range at any supply voltage.
• High slew rate = 10V/µs
• Rail-to-rail operation
The EL5221C also features fast slewing and settling times, as well as
a high output drive capability of 30mA (sink and source). These fea-
tures make the EL5221C ideal for use as voltage reference buffers in
Thin Film Transistor Liquid Crystal Displays (TFT-LCD). Other
applications include battery power, portable devices, and anywhere
low power consumption is important.
Applications
• TFT-LCD drive circuits
• Electronics notebooks
• Electronics games
The EL5221C is available in space-saving SOT23-6 and MSOP-8
packages and operates over a temperature range of -40°C to +85°C.
• Personal communication devices
• Personal Digital Assistants (PDA)
• Portable instrumentation
• Wireless LANs
• Office automation
• Active filters
• ADC/DAC buffer
