General Description
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.
