Low power consumption and a shutdown facility (ADM3222/ADM35) make them ideal for battery-powered portable instruments. The ADM3202/ADM3222/ADM35 parts conform to the EIA-232E and CCITT V.2 specifications and operate at data rates up to 460 kbps. Four external 0. μf charge pump capacitors are used for the voltage doubler/inverter, permitting operation from a single 3.3 V supply. The ADM3222 contains additional enable and shutdown circuitry. The EN input can be used to three-state the receiver outputs. The SD input is used to power down the charge pump and transmitter outputs, reducing the quiescent current to less than 0.5 μa. The receivers remain enabled during shutdown unless disabled using EN. The ADM35 contains a driver disable mode and a complete shutdown mode. The ADM3202 is available in a 6-lead PDIP, SOIC_W, and SOIC_N, as well as a space-saving 6-lead TSSOP. The ADM3222 is available in -lead PDIP and SOIC_W and in 20-lead SSOP and TSSOP. The ADM35 is available in a 20-lead SSOP, which is pin-compatible with the LTC35 CG.

GENERAL DESCRIPTION The ADM3202/ADM3222/ADM35 are RS-232 line drivers/ receivers. Step-up voltage converters coupled with level-shifting transmitters and receivers allow RS-232 levels to be developed while operating from a single 3.3 V supply. technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications. The ADM3202/ADM3222/ADM35 are modifications, enhancements, and improvements of the AD230 to AD24 family and derivatives. They are essentially plug-in compatible and do not have any materially different applications. CIRCUIT DESCRIPTION The internal circuitry consists of these main sections: A charge pump voltage converter 3.3 V logic to EIA-232 transmitters EIA-232 to 5 V logic receivers Charge Pump DC to DC Voltage Converter The charge pump voltage converter consists of a 200 khz oscillator and a switching matrix. The converter generates a ±6.6 V supply from the input 3.3 V level. This is done in two stages by using a switched capacitor technique as illustrated in Figure and Figure 9. First, the 3.3 V input supply is doubled to 6.6 V by using Capacitor C as the charge storage element. The 6.6 V level is then inverted to generate 6.6 V using C2 as the storage element. C3 is shown connected between V and VCC but is equally effective if connected between V and. Capacitors C3 and C4 are used to reduce the output ripple. Their values are not critical and can be increased, if desired. Capacitor C3 is shown connected between V and VCC. It is also acceptable to connect this capacitor between V and. If desired, larger capacitors (up to 0 μf) can be used for Capacitors C to C4. 3.3V INPUT INPUTS INPUTS T IN T2 IN R OUT R2 OUT EN C C C2 C2 T 3.3V TO 6.6V DOUBLER 6.6V TO 6.6V INVERTER T2 R V R2 ADM3222 V 3.3V INPUT SD C3 6.3V C4 T OUT T2 OUT R IN R2 IN C5 INPUTS* *INTERNAL 5kΩ PULL-DOWN RESISTOR ON EACH RS-232 INPUT Figure 6.

Transmitter (Driver) Section The drivers convert 3.3 V logic input levels into RS-232 output levels. With VCC = 3.3 V and driving an RS-232 load, the output voltage swing is typically ±6 V. Receiver Section The receivers are inverting level-shifters that accept RS-232 input levels and translate them into 3 V logic output levels. The inputs have internal 5 kω, pull-down resistors to ground and are protected against overvoltages up to ±30 V. Unconnected inputs are pulled to 0 V by the internal 5 kω, pull-down resistor. This results in a Logic output level for unconnected inputs or for inputs connected to. HIGH BAUD RATE The ADM3202/ADM3222 feature high slew rates permitting data transmission at rates well in excess of the EIA/RS-232E specifications. RS-232 voltage levels are maintained at data rates up to 460 kbps even under worst-case loading conditions. This allows high speed data links between two terminals and is suitable for the new generation ISDN modem standards that require data rates of 230 kbps. The slew rate is internally controlled to less than 30 V/μs to minimize EMI interference. The receivers have Schmitt-trigger inputs with a hysteresis level of 0.4 V. This ensures error-free reception for both noisy inputs and for inputs with slow transition times. Rev. E Page 9 of 6
