APPLICATIO S I FOR ATIO
Detecting Pulses
The front page shows a circuit for detecting very fast
pulses. In this open-loop design, the detector diode is D1
and a level shifting or compensating diode is D2. A load
resistor R
resistor R
value resistors ensure that the diode drops are equal. A
very fast pulse will exceed the amplifier slew rate and
cause a long overload recovery time. Some amount of
dV/dt limiting on the input can help this overload condi-
tion, however too much will delay the response. Also
shown is the response to a 4V
The maximum output slew rate in the photo is 30V/µs. This
rate is set by the 30mA current limit driving 1000pF.
Operation on Single 5V Supply
The LT1195 has been optimized for a single 5V supply.
This circuit amplifies standard composite video (1V
including sync) by 2 and drives a double-terminated 75Ω
cable. Resistors R1 and R2 bias the amplifier at 2V,
allowing the sync pulses to stay within the common mode
range of the amplifier. Large coupling capacitors are
required to pass the low frequency sidebands of the
composite signal. A multiburst response and vector plot
standard color burst are shown.
