The ADM101E is a single-channel RS-232 driver and receiver in the
Analog Devices Craft Port™ series, designed to operate from a
single +5 V supply. A highly efficient charge-pump voltage
inverter generates an on-chip –5 V supply, which eliminates the
need for a negative power supply for the driver, and permits
RS-232 compatible output levels to be developed using chargepump
capacitors as small as 0.1 µF.
