The LT(R)1190 is a video operational amplifier optimized for operation on 5V, and a single 5V supply. Unlike many high speed amplifiers, this amplifier features high openloop gain, over 85dB, and the ability to drive heavy loads to a full-power bandwidth of 20MHz at 7VP-P. In addition to its very fast slew rate, the LT1190 features a unitygain-stable bandwidth of 50MHz and a 75 phase margin, making it extremely easy to use. Because the LT1190 is a true operational amplifier, it is an ideal choice for wideband signal conditioning, fast integrators, active filters, and applications requiring speed, accuracy and low cost. The LT1190 is available in 8-pin PDIP 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: Absolute maximum ratings are those values beyond which the life of the device may be impaired. Note 2: A heat sink is required to keep the junction temperature below absolute maximum when the output is shorted. 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 a 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. AV = -1, RL = 1k. Note 7: NTSC (3.58MHz). For RL = 1k, Diff AV = 0.1%, Diff Ph = 0.06. Note 8: See Applications 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 (J and N suffix) and are sample tested on every lot of the SO packaged parts (S suffix).

Power Supply Bypassing
The LT1190 is quite tolerant of power supply bypassing. In some applications a 0.1F ceramic disc capacitor placed 1/2 inch from the amplifier is all that is required. A scope photo of the amplifier output with no supply bypassing is used to demonstrate this bypassing tolerance, RL = 1k.
No Supply Bypass Capacitors
LT1190 * TA04
AV = -1, IN DEMO BOARD, RL = 1k
Supply bypassing can also affect the response in the frequency domain. It is possible to see a slight 1dB rise in the frequency response at 130MHz depending on the gain configuration, supply bypass, inductance in the supply leads and printed circuit board layout. This can be further minimized by not using a socket.

In most applications, and those 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. Two oscilloscope photos with different bypass conditions are used to illustrate the settling time characteristics of the amplifier. Note that although the output waveform looks acceptable at 1V/DIV, when amplified to 1mV/DIV the settling time to 2mV is 4.244s for the 0.1F bypass; the time drops to 163ns with multiple bypass capacitors.

Cable Terminations
The LT1190 operational amplifier has been optimized as a low cost video cable driver. The 50mA guaranteed output current enables the LT1190 to easily deliver 7.5VP-P into 100, while operating on 5V supplies or 2.6VP-P on a single 5V supply.

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 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. The cable driver has a - 3dB bandwidth in excess of 30MHz while driving the 150 load.
U
Using the Shutdown Feature The LT1190 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 shut down 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 400ns. This shutoff can be under the control of HC CMOS operating between 0V and - 5V.

The ability to maintain shutoff is shown on the curve Shutdown Supply Current vs Temperature in the Typical Performance Characteristics section. At very high elevated temperatures it is important to hold the shutdown pin close to the negative supply to keep the supply current from increasing. Murphy Circuits There are several precautions the user should take when using the LT1190 in order to realize its full capability. Although the LT1190 can drive a 50pF load, isolating the capacitance with 10 can be helpful. Precautions primarily have to do with driving large capacitive loads.

Other precautions include: 1. Use a ground plane (see Design Note 50, High Frequency Amplifier Evaluation Board). 2. Do not use high source impedances. The input capacitance of 2pF and RS = 10k for instance, will give an 8MHz - 3dB bandwidth. 3. PC board socket may reduce stability. 4. A feedback resistor of 1k or lower reduces the effects of stray capacitance at the inverting input. (For instance, closed-loop gain of 2 can use RFB = 300 and RG = 300.)
