inverting input (A1) senses the shield and the non-invert-
ing input (A2) senses the center conductor. Since this
amplifier does not load the cable (take care to minimize
stray capacitance) and it rejects common mode hum and
noise, several amplifiers can sense the signal with only
one termination at the end of the cable. The design
equations are simple. Just select the gain you need (it
should be two or more) and the value of the feedback
resistor (typically 1k) and calculate RG1 and RG2. The gain
can be tweaked with RG2 and the CMRR with RG1 if needed.
The bandwidth of the noninverting input signal is not
reduced by the presence of the other amplifier, however,
the inverting input signal bandwidth is reduced since it
passes two amplifiers. The CMRR is good at high frequen-
cies because the bandwidth of the amplifiers are about the
same even though they do not necessarily operate at the
same gain.
Summing Amplifier (DC Accurate)
The summing amplifier is easily made by adding additional
inputs to the basic inverting amplifier configuration. The
LT1223 has no IOS spec because there is no correlation
between the two input bias currents. Therefore, we will not
improve the DC accuracy of the inverting amplifier by
putting in the extra resistor in the noninverting input.
Difference Amplifier
The LT1223 difference amplifier delivers excellent
performance if the source impedance is very low. This is
because the common mode input resistance is only equal
to RF + RG.
Video Instrumentation Amplifier
This instrumentation amplifier uses two LT1223s to in-
crease the input resistance to well over 1M. This makes an
excellent “loop through” or cable sensing amplifier if the
Cable Driver
The cable driver circuit is shown on the front page. When
driving a cable it is important to properly terminate both
ends if even modest high frequency performance is
required. The additional advantage of this is that it isolates
the capacitive load of the cable from the amplifier so it can
operate at maximum bandwidth.
