... The S.O. (M) package must have pin 4 and at least one of pins 1,8, connected to V− for proper operation. Note 4: Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowable junction temperature of 150˚C. Each am- plifier of the LM6182 is short circuit current limited to 100 mA typical. Note 5: Typical values represent the most likely parametric norm. ...

... Figure 3A and Figure 3B illustrate the effect of increasing R closed-loop gain – the amplifier bandwidth decreases. Ac- cordingly, larger feedback resistors can be used to slow down the LM6182 and reduce overshoot in the time domain response. Conversely, smaller feedback resistance values than 820 can be used to compensate for the reduction of bandwidth at high closed-loop gains, due to 2nd order ef- fects ...

... The LM6182 current feedback amplifier does not require this lead compensation capacitor and has an even simpler, more elegant solution. To limit the bandwidth and peaking of the LM6182 current DS011926-26 feedback amplifier, do not use a capacitor across R Figure 7 . This actually has the opposite effect and extends the bandwidth of the amplifier leading to possible instability ...

... The LM6182 can drive significantly larger capacitive loads than many current feedback amplifiers. This is extremely valuable for simplifying the design of coax-cable drivers. Al- though the LM6182 can directly drive as much as 100 pF of load capacitance without oscillating, the resulting response will be a function of the feedback resistor value. Figure 9B il- lustrates the small-signal pulse response of the LM6182 while driving load ...

... The LM6182 has an excellant crosstalk rejection value MHz. This value is made possible because the LM6182 amplifiers share no common circuitry other than the supply. High frequency crosstalk that does appear is prima- rily caused by the magnetic and capacitive coupling of the in- ternal bond wires ...
Page 20
... The LM6182 crosstalk effect is minimized in applications that cascade the amplifiers by preceding amplifier A with ampli- fier B. START-UP TIME Using the circuit in Figure 13 , the LM6182 demonstrated a start-up time of 50 ns. FIGURE 13.

... Using a voltage feedback amplifier, the bandwidth of the summing circuit in Figure 20 is limited by the highest gain needed for either signal V1 or V2. If the LM6182 amplifier is used instead, wide circuit bandwidth can be maintained rela- tively independent of gain requirements. ...
