Gain-Bandwidth Product Unity-Gain Stable Slew Rate Output Current Low Supply Current High Open-Loop Gain Low Cost Single Supply 5V Operation Industry Standard Pinout Output Shutdown
The LTC1195 is a video operational amplifier optimized for operation on single 5V and 5V supply. Unlike many high speed amplifiers, the LT1195 features high open-loop gain, over 75dB, and the ability to drive heavy loads to a full power bandwidth of 8.5 MHz at 6VP-P. The LT1195 has a unity-gain stable bandwidth of 50MHz, and a 60 phase margin, and consumes only 12mA of supply current, making it extremely easy to use. Because the LT1195 is a true operational amplifier, it is an ideal choice for wideband signal conditioning, fast integrators, peak detectors, active filters, and applications requiring speed, accuracy, and low cost. The LT1195 is a low power version of the popular LT1190, and is available in 8-pin miniDIPs and SO packages with standard pinouts. The normally unused pin 5 is used for a shutdown feature that shuts off the output and reduces power dissipation to a mere 15mW.

Note 1: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted continuously. Note 2: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formats: LT1195MJ8, LT1195CJ8: TJ = TA + (PD x 100C/ W) LT1195N: TJ = TA + (PD x 100C/ W) LT1195CS: TJ = TA + (PD x 150C/ W) Note 3: Exceeding the input common-mode range may cause the output to invert. Note 4: Slew rate is measured between 1V on the output, with 3V input step. Note 5: Full power bandwidth is calculated from the slew rate measurement: FPBW = SR/2VP.
Note 6: Settling time measurement techniques are shown in "Take the Guesswork Out of Settling Time Measurements," EDN, September 19, 1985. Note 7: NTSC (3.58MHz). For RL = 1k, Diff AV = 0.3%, Diff Ph = 0.35. Note 8: See Applications Information section for shutdown at elevated temperatures. Do not operate the shutdown above TJ > 125C. Note 9: AC parameters are 100% tested on the ceramic and plastic DIP packaged parts (J8 and N8 suffix) and are sample tested on every lot of the SO packaged parts (S8 suffix). Note 10: Do not operate at AV < 2 for TA < 0C.

Power Supply Bypassing The LT1195 is quite tolerant of power supply bypassing. In some applications a 0.1F ceramic disc capacitor placed 0.5 inches from the ampifier is all that is required. In applications requiring good settling time, it is important to use multiple bypass capacitors. A 0.1F ceramic disc in parallel with a 4.7F tantalum is recommended. Cable Terminations The LT1195 operational amplifier has been optimized as a low cost video cable driver. The 20mA guaranteed output current enables the LT1195 to easily deliver 6VP-P into 150, while operating on 5V supplies.

When driving a cable it is important to terminate the cable to avoid unwanted reflections. This can be done in one of two ways: single termination or double termination. With single termination, the cable must be terminated at the
8
U
receiving end (75 to ground) to absorb unwanted energy. The best performance can be obtained by double termination (75 in series with the output of the amplifier, and 75 to ground at the other end of the cable). This termination is preferred because reflected energy is absorbed at each end of the cable. When using the double termination technique it is important to note that the signal is attenuated by a factor of 2, or 6dB. This can be compensated for by taking a gain of 2, or 6dB in the amplifier. Using the Shutdown Feature The LT1195 has a unique feature that allows the amplifier to be shut down for conserving power, or for multiplexing several amplifiers onto a common cable. The amplifier will shutdown by taking pin 5 to V -. In shutdown, the amplifier dissipates 15mW while maintaining a true high impedance output state of 15k in parallel with the feedback resistors. The amplifiers must be used in a noninverting configuration for MUX applications. In inverting configurations the input signal is fed to the output through the feedback components. The following scope photos show that with very high RL, the output is truly high impedance; the output slowly decays toward ground. Additionally, when the output is loaded with as little as 1k the amplifier shuts off in 700ns. This shutoff can be under the control of HC CMOS operating between 0V and -5V.

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 RL is connected to -5V, and an identical bias resistor RB is used to bias the compensating diode. Equal 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 condition, however too much will delay the response. Also shown is the response to a 4VP-P input that is 150ns wide. The maximum output slew rate in the photo is 30V/s. 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 (1VP-P including sync) by 2 and drives a double-terminated 75 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.

Send Color Video Over Twisted-Pair With an LT1195 it is possible to send and receive color composite video signals more than 1000 feet on a low cost twisted-pair. A bidirectional "video bus" consists of the LT1195 op amp and the LT1187 video difference amplifier. A pair of LT1195s at TRANSMIT 1, is used to generate differential signals to drive the line which is back-terminated in its characteristic impedance. The LT1187, twisted-pair receiver, converts signals from differential to single-ended. Topology of the LT1187 provides for cable compensation at the amplifier's feedback node as shown. In this case, 1000 feet of twisted-pair is compensated with 1000pF and 50 to boost the 3dB bandwidth of the system from 750kHz to 4MHz. This bandwidth is adequate to pass a 3.58MHz chrome subcarrier, and the 4.5MHz sound subcarrier. Attenuation in the cable can be compensated by lowering the gain set resistor RG. At TRANSMIT 2, another pair of LT1195s serve the dual function to provide cable termination via low output impedance, and generate differential signals for TRANSMIT 2. Cable termination is made up of 15 and 33 attentuator to reduce the differential input signal to the LT1187. Maximum input signal for the LT1187 is 760mVP-P.
