ISL55001 Product Description setting is greater than 1, the gain resistor RG can then be chosen to make up for any gain loss which may be The ISL55001 is a wide bandwidth, low power, and low created by the additional series resistor at the output. offset voltage feedback operational amplifier. This device is internally compensated for closed loop gain of +1 or When used as a cable driver, double termination is greater. Connected in voltage follower mode and driving always recommended for reflection-free performance. a 500 load, the -3dB bandwidth is around a 220MHz. For those applications, a back-termination series resistor Driving a 150 load and a gain of 2, the bandwidth is at the amplifier's output will isolate the amplifier from the about 90MHz while maintaining a 300V/µs slew rate. cable and allow extensive capacitive drive. However, other applications may have high capacitive loads The ISL55001 is designed to operate with supply voltage without a back-termination resistor. Again, a small series from +15V to -15V. That means for single supply resistor at the output can help to reduce peaking. application, the supply voltage is from 0V to 30V. For split supplies application, the supply voltage is from ±15V. Output Drive Capability The amplifier has an input common-mode voltage range The ISL55001 does not have internal short circuit from 1.5V above the negative supply (VS- pin) to 1.5V protection circuitry. It has a typical short circuit current of below the positive supply (VS+ pin). If the input signal is 140mA. If the output is shorted indefinitely, the power outside the above specified range, it will cause the output dissipation could easily overheat the die or the current signal to be distorted. could eventually compromise metal integrity. Maximum The outputs of the ISL55001 can swing from -12.75V to reliability is maintained if the output current never +13.4V for VS = ±15V. As the load resistance becomes exceeds ±60mA. This limit is set by the design of the lower, the output swing is lower. internal metal interconnect. Note that in transient applications, the part is robust. Choice of Feedback Resistor and Gain Bandwidth Product Short circuit protection can be provided externally with a back match resistor in series with the output placed close For applications that require a gain of +1, no feedback as possible to the output pin. In video applications this resistor is required. Just short the output pin to the would be a 75 resistor and will provide adequate short inverting input pin. For gains greater than +1, the circuit protection to the device. Care should still be taken feedback resistor forms a pole with the parasitic not to stress the device with a short at the output. capacitance at the inverting input. As this pole becomes Power Dissipation smaller, the amplifier's phase margin is reduced. This causes ringing in the time domain and peaking in the With the high output drive capability of the ISL55001, it frequency domain. Therefore, RF can't be very big for is possible to exceed the +150°C absolute maximum optimum performance. If a large value of RF must be junction temperature under certain load current used, a small capacitor in the few Pico Farad range in conditions. Therefore, it is important to calculate the parallel with RF can help to reduce the ringing and maximum junction temperature for an application to peaking at the expense of reducing the bandwidth. For determine if load conditions or package types need to be gain of +1, RF = 0 is optimum. For the gains other than modified to assure operation of the amplifier in a safe +1, optimum response is obtained with RF with proper operating area. selection of RF and RG (see Figures 15 and 16 for The maximum power dissipation allowed in a package is selection). determined according to Equation 1: Video Performance T –T PD = ----J---M-----A----X--------------A---M-----A----X--- (EQ. 1) For good video performance, an amplifier is required to MAX JA maintain the same output impedance and the same frequency response as DC levels are changed at the Where: output.

If V less peaking is desired in applications, a small series PDMAX = (VS+ –VS-ISMAX+ VS+ –VOUTi R-------O----U----T----i-- resistor (usually between 5 to 50) can be placed in i=1 LOADi series with the output to eliminate most peaking.

As the strain variable is converted into an output voltage (see Figure 28). component resistor in the balanced bridge is subjected +V2 5V - C6 VARIABLE SUBJECT TO 1nF 1k V5+ R15 R16 R17 1k + V+ 0V 1k 1k - 1k R18 1k - V- R1kLV(VO1U+TV2+V3+V4) RF 1k C12 1nF + V4 - 5V FIGURE 28.
