CONDITIONS
RL = 10 kΩ; CL = 50 pF
(see Fig.14)
RL = 10 kΩ; CL = 50 pF
(see Fig.14)
RL = 600 Ω; CL = 50 pF
(see Figs 12 and 15)
RL = 600 Ω; CL = 50 pF;
f = 1 MHz (E1, E2 or Sn,
square-wave between VCC
and GND, tr = tf = 6 ns)
(see Fig.16)
RL = 50 Ω; CL = 10 pF
(see Figs 13 and 14)
Notes to AC characteristics
1. Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 Ω).
2. Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 Ω).
Vis is the input voltage at a Yn or Z terminal, whichever is assigned as an input.
Vos is the output voltage at a Yn or Z terminal, whichever is assigned as an output.
Test conditions:
VCC = 4.5 V; GND = 0 V; VEE = −4.5 V;
RL = 50 Ω; Rsource = 1 kΩ.
