OUPUT IMPEDANCE IN POWER DOWN MODE
In Power Down Mode the output of the driver is in
"high impedance" state. It is really the case for the
static mode. Regarding the dynamic mode, the im-
pedance decreases due to a capacitive effect of
the collector-substrat and base collector junction.
The impedance behaviour comes capacitive, typi-
cally: 1.4M
// 33pF.
INTERMODULATION DISTORTION
The curves shown below are the measurements
results of a single operator wired as an adder with
a gain of 15dB.
The operational amplifier is supplied by a symmet-
ric
±
6V and is loaded with 25
.
Two synthesizers (Rhode & Schwartz SME) gen-
erate two frequencies (tones) (70 & 80kHz or 180
& 280kHz).
An HP3585 spectrum analyzer measures the spu-
rious level at different frequencies.
The curves are traced for different output levels
(the value in the X ax is the value of each tone).
The output levels of the two tones are the same.
The generators and spectrum analyzer are phase
locked to enhance measurement precision.
