data sheet ada4432-1/ada4433-1 rev. a | page 15 of 28 theory of operation the ada4432 -1 and ada4433 -1 with short - to - battery and short - to - ground protection are designed as fifth - order , low - pass filters with a fixed gain of 2 that is capable of driving 2 v p - p video signals into doubly terminated video transmission line s on a single supply as low as 2.6 v. the filter has a 1 db flatness of 9 mhz and provid es a typical out - of - band rejection of 45 db at 27 mhz . the ada4432 -1 is a single - ended filter/driver that can be used with both ac - and dc - coupled inputs and outputs, with an input range that includ es ground for use with a ground referenced digital - to - analog converter ( dac ) in a single - supply application. to ensure accurate reproduction of ground referenced signals without saturating the output devices , an internal offset is added to shift the output voltage up by 200 mv. the ada4433 -1 is a fully differential filter /driver that is also designed for compliance with both ac - and dc - coupled inpu ts and outputs. the ada4433 -1 can be driven by a differential or single - ended source and provide s a fully differential output signal that is bias ed at a voltage equal to half the supply voltage ( +v s /2 ). when the device is used with a single - ended input source, bias the inverting input , ? in , at the middle of the input voltage range applie d to the noninverting input , +in, allowing each output signal to swing equally around the midsupply point (see the configuring the ada4433 -1 for single - ended input signals section ). this is particularly important to maximize output voltage headroom in low supply voltage applications. s hort circuit (short - to - ground ) protection both the ada4432 -1 and ada4433 -1 include internal protection circuits that limit the output sink or sou rce current to 6 0 ma. this short circuit protection prevents damage to the ada4432 -1 and ada4433 -1 when the output(s) are shorted to ground, to a low impedance source, or together (in the case of the ada4433 -1 ) for an extended time . in addition, in the case of the ada4433 -1 , the total sink or source current for both outputs is limited to 50 ma, which helps protect the device in the event of both outputs being shorted to a low impedance . however, short circuit protection does not affect the normal operation of the devices beca use one output sources current , whe reas the other output sinks current when driving a differential output signal . overvoltage (short - to - battery) protection both the ada4432 -1 and ada4433 -1 include internal protection cir cuits to ensure that internal circuitry is not subjected to extreme voltages or currents during an overvoltage event applied to their outputs. a short - to - battery condition usually consists of a voltage on the outputs that is significantly higher than the power supply voltage of the amplifier. duration can vary from a short transient to a continuous fault. the ada4432 -1 and ada4433 -1 can withstand voltages of up to 18 v on the outputs. critical internal nodes are protected from exposure to high voltages by circuitry that isolates the output devices from the high voltage and limits internal currents. th is protection is available whether the device is enabled or disabled, even when the supply voltage is removed. the output devices are disconnected when the voltage at the output pins exceeds the supply voltage. after the overvoltage condition is removed, internal circuitry pulls t he output voltage back within normal operating levels . the output devices are reconnected when the voltage at the output pins falls below the supply voltage by about 300 mv. when the devices are used with a doubly terminated cable, the voltage sensed at the output pins is lower than the voltage applied to the cable by the voltage drop across the back termination resistor. the maxim um voltage drop a cross the back termination resistor is limited by the short - circuit c urrent protection ; therefore, the threshold at which the over - voltage protection respond s to a voltage applied to the cable is v thresh (cable) = +v s + i limit r t w here: v thresh (cable) is the voltage applied to the cable that activate s the internal isolation circuitry. +v s is the positive supply voltage. i l imit is the internal short - circuit current limit, typically 50 ma. r t the back termination resistance. if the voltage applied to the cable is lower than v thresh (cable) , the voltage seen at the output pins is lower than the supply voltage, so no overvoltage condition is detected . h owever, the internal circuitry is protected by the short circuit current limit ; therefore, the ada4432 -1 / ada4433 -1 can withstand an indefinite duration short to any positive voltage up to 18 v without damage. short - to - battery output flag in addition to the internal protection circuitry, the short - to - battery output flag (stb pin) indicates an overvoltage condition on either or both output pins. the flag is present whenever the internal overvoltage protection is active ; therefore, it is available when the device is enabled or disabled. it is no t available, however, when the supply voltage is removed, al though the internal protection is still active. the threshold at which the short - to - battery flag is activated and deactivated is the same as the threshold for the protection circuitry. table 8 . stb p in logic stb pin output device state high (logic 1) overvoltage fault condition low (logic 0) normal o peration
