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.
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.
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.

All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication; however, this data sheet cannot be a “controlled document”. Current revisions, if any, to these
specifications are maintained at the factory and are available upon your request. We recommend checking the revision level before finalization of your design documentation.
Values beyond absolute maximum ratings can cause the device to be pre-
