... Low distortion is preserved over the many possible differ- ential and common-mode voltages at the input and output. Good gain flatness and excellent differential gain of 0.06% and phase of 0.08 make the AD830 suitable for many video system applications. Furthermore, the AD830 is suited for general pur- pose signal processing from MHz. ...

... Its topology, discussed in detail in a later section, by design acts = V – difference amplifier. The circuit of Figure 20 shows how simply the AD830 is configured to produce the difference of two signals V and V 1 exactly reproduced at the output relative to a separate output common. Any common-mode voltage present at the input is removed by the AD830. V ...

... It is important to note that the bandwidth and general dy- namic behavior is symmetrical (identical) for the noninverting and the inverting connections of the AD830. In addition, the input im- V OUT pedance and CMRR are the same for either connections. This is ...

... AD830 INTERFACING THE INPUT Common-Mode Voltage Range The common-mode range of the AD830 is defined by the am- plitude of the differential input signal and the supply voltage. The general definition of common-mode voltage, V ally applied to a symmetrical differential signal centered about a particular voltage as illustrated by the diagram in Figure 23. ...

... Applying Feedback The AD830 is intended for use with gain from 1 to 100. Gains greater than one are simply set by a pair of resistors connected as shown in the difference amplifier (Figure 35) with gain >1. ...

... In situations where the signal lies at a common voltage outside the common mode range of the AD830 direct coupling will not work coupling should be used. A tested application included later in this data sheet (Figure 42), shows how to easily accomplish cou- pling to the AD830 ...

... Some applications, such as A/D drivers, require that the signal be amplified and also offset, typically to accommodate the input range of the device. The AD830 can offset the output signal very simply through Pin 3 even with gain > 1. The voltage ap- plied to Pin 3 must be attenuated by an appropriate factor so that desired offset ...

... AD830 Loop Through or Line Bridging Amplifier (Figure 37) The AD830 is ideally suited for use as a video line bridging am- plifier. The video signal is tapped from the conductor of the cable relative to its shield. The high input impedance of the AD830 provides negligible loading on the cable. More signifi- cantly, the benign loading is maintained while the AD830 is powered-down ...

... Figure 42. A simple resistive network at the X G input establishes a common-mode bias. Here, the common mode is centered at 6 volts, but in principle can be any voltage within the common-mode limits of the AD830. The 10 k re- sistors to each input bias the X G stage with sufficiently high ...
