TYPICAL APPLICATION DATA
output characteristics
All operating characteristics are specified with 100-pF load capacitance. These amplifiers will drive higher
capacitive loads; however, as the load capacitance increases, the resulting response pole occurs at lower
frequencies, thereby causing ringing, peaking, or even oscillation. The value of the load capacitance at which
oscillation occurs varies with production lots. If an application appears to be sensitive to oscillation due to load
capacitance, adding a small resistance in series with the load should alleviate the problem. Capacitive loads
of 1000 pF and larger may be driven if enough resistance is added in series with the output (see Figure 43).
(a) CL = 100 pF, R = 0
(b) CL = 300 pF, R = 0
(c) CL = 350 pF, R = 0
(d) CL = 1000 pF, R = 0
(e) CL = 1000 pF, R = 50
(f) CL = 1000 pF, R = 2 k
