CLC520
Amplifier with Voltage Controlled Gain, AGC +Amp
General Description
The CLC520 is a wideband DC-coupled amplifier with volt-
age controlled gain (AGC). The amplifier has a high imped-
ance, differential signal input; a high bandwidth, gain control
input; and a single-ended voltage output. Signal channel
performance is outstanding with 160MHz small signal band-
width, 0.5 degree linear phase deviation (to 60MHz) and
0.04% signal nonlinearity at 4V
Gain control is very flexible and easy to use. Maximum gain
may be set over a nominal range of 2 to 100 with one
external resistor. In addition, the gain control input provides
more than 40dB of voltage controlled gain adjustment from
the maximum gain setting. For example, a CLC520 may be
set for a maximum gain of 2 (or 6dB) for a voltage controlled
gain range from 40dB to less than 34dB. Alternatively, the
CLC520 could be set for a maximum gain of 100 or (40dB)
for a voltage controlled gain range from 40dB to less than
0dB.
The gain control bandwidth of 100MHz is superb for AGC/
ALC loop stabilization. And since the gain is minimum with a
zero volt input and maximum with a +2 volt input, driving the
control input is easy.
Finally, the CLC520 differential inputs, and ground refer-
enced voltage output take the trouble out of designing
DC-coupled AGC circuits for display normalizers; signal lev-
eling automatic circuits; etc.
