All members of the ADM230L family, except the ADM231L and the ADM239L, include two internal charge pump voltage converters that allow operation from a single +5 V supply. These converters 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 for the AD2xx familyfeaturing lower power consumption, faster slew rate and operationwith smaller (1 µF) capacitors.
