10 / 16 page  10 LT1210 1210fa S APPLICATI I FOR ATIO When the LT1210 is used to drive capacitive loads, the available output current can limit the overall slew rate. In the fastest configuration, the LT1210 is capable of a slew rate of over 1V/ns. The current required to slew a capacitor at this rate is 1mA per picofarad of capacitance, so 10,000pF would require 10A! The photo (Figure 6) shows the large-signal behavior with CL = 10,000pF. The slew rate is about 150V/ µs, determined by the current limit of 1.5A. the bandwidth is reduced. The photos in Figures 5a, 5b and 5c show the large-signal response of the LT1210 for various gain configurations. The slew rate varies from 770V/ µs for a gain of 1, to 1100V/µs for a gain of –1. 1210 F05c RF = RG = 750Ω RL = 10Ω Figure 5c. Large-Signal Response, AV = 2 Figure 5a. Large-Signal Response, AV = 1 1210 F05a RF = 825Ω RL = 10Ω VS = ±15V RF = RG = 750Ω RL = 10Ω VS = ±15V 1210 F05b 1210 F06 RF = RG = 3k RL = ∞ VS = ±15V Differential Input Signal Swing The differential input swing is limited to about ±6V by an ESD protection device connected between the inputs. In normal operation, the differential voltage between the input pins is small, so this clamp has no effect; however, in the shutdown mode the differential swing can be the same as the input swing. The clamp voltage will then set the maximum allowable input voltage. To allow for some margin, it is recommended that the input signal be less than ±5V when the device is shut down. Capacitance on the Inverting Input Current feedback amplifiers require resistive feedback from the output to the inverting input for stable operation. Take care to minimize the stray capacitance between the output and the inverting input. Capacitance on the invert- ing input to ground will cause peaking in the frequency response (and overshoot in the transient response), but it does not degrade the stability of the amplifier.
