FEATURES

1. ZIN = 1012Ω (Min).

2. ZOUT = 0.01Ω (Max), B.W. = 12MHz (Typ).

3. Slew Rate = 4V/µs (Min), Output Swing = ±10V (Min) to 50kHz.

NOTE: A small load capacitance is recommended in all applications where practical to prevent possible high frequency oscillations resulting from

external wiring parasitics. Capacitance up to 100pF has negligible effect on the bandwidth or slew rate.
