GENERAL DESCRIPTION
The ADM2xx family of line drivers/receivers is intended for all
EIA-232-E and V.28 communications interfaces, especially in
applications in which 12 V is not available. The ADM236L and
ADM241L feature a low power shutdown mode that reduces
power dissipation to less than 5 W, making them ideally suited
for battery-powered equipment. The ADM233L does not
require any external components and is particularly useful in
applications where printed circuit board space is critical.
All members of the ADM2xxL family, except the ADM231L and
ADM239L, include two internal charge pump voltage converters
that allow operation from a single 5 V supply. These parts convert
the 5 V input power to the ±10 V required for RS-232 output

levels. The ADM231L and ADM239L are designed to operate
from 5 V and 12 V supplies. An internal +12 V to 12 V charge
pump voltage converter generates the 12 V supply.
The ADM2xxL is an enhanced upgrade to the AD2xx family. It
features lower power consumption, faster slew rate, and the
ability to operate with smaller (1 F) capacitors.
