ADM205–ADM211/ADM213  
The ADM205, ADM206, ADM211, and ADM213 are particu-  
larly useful in battery powered systems as they feature a low  
power shutdown mode which reduces power dissipation to less  
than 5 µW.

The ADM205 is designed for applications where space saving is  
important as the charge pump capacitors are molded into the  
package.  
The ADM209 includes only a negative charge pump converter  
and are intended for applications where a positive 12 V is available.

To facilitate sharing a common line or for connection to a mi-  
croprocessor data bus the ADM205, ADM206, ADM209,  
ADM211 and ADM213 feature an enable (EN) function. When  
disabled, the receiver outputs are placed in a high impedance  
state.

CIRCUIT DESCRIPTION  
The internal circuitry in the ADM205-ADM211 and ADM213  
consists of three main sections. These are:  
(a) A charge pump voltage converter  
(b) RS-232 to TTL/CMOS receivers  
(c) TTL/CMOS to RS-232 transmitters

Charge Pump DC-DC Voltage Converter  
The charge pump voltage converter consists of an oscillator and  
a switching matrix. The converter generates a ±10 V supply  
from the input 5 V level. This is done in two stages using a  
switched capacitor technique as illustrated in Figures 23 and 24.  
First, the 5 V input supply is doubled to 10 V using capacitor  
C1 as the charge storage element. The 10 V level is then in-  
verted to generate –10 V using C2 as the storage element.

GENERAL INFORMATION  
The ADM205-ADM211 and ADM213 family of RS-232 driv-  
ers/receivers are designed to solve interface problems by meeting  
the EIA-232-E specifications while using a single digital +5 V  
supply. The EIA-232-E standard requires transmitters which  
will deliver ±5 V minimum on the transmission channel and re-  
ceivers which can accept signal levels down to ±3 V. The  
ADM205-ADM211 and ADM213 meet these requirements by  
integrating step up voltage converters and level shifting trans-  
mitters and receivers onto the same chip. CMOS technology is  
used to keep the power dissipation to an absolute minimum. A  
comprehensive range of transmitter/receiver combinations is  
available to cover most communications needs. The ADM205–  
ADM211 and ADM213 are modifications, enhancements and  
improvements to the AD230–AD241 family and derivatives  
thereof. They are essentially plug-in compatible and do not have  
materially different applications.

Capacitors C3 and C4 are used to reduce the output ripple.  
Their values are not critical and can be reduced if higher levels  
of ripple are acceptable. The charge pump capacitors C1 and  
C2 may also be reduced at the expense of higher output imped-  
ance on the V+ and V– supplies.  
The V+ and V– supplies may also be used to power external cir-  
cuitry if the current requirements are small.
