Unlike many high speed amplifiers, this amplifier features high openloop gain, over 100dB, 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 LT1192 has a high gain bandwidth of 350MHz and is compensated for a closedloop gain of 5 or greater. Because the LT1192 is a true operational amplifier, it is an ideal choice for wideband signal conditioning, active filters, and applications requiring speed, accuracy and low cost.

In some applications a 0.1µF 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. In most applications, and those requiring good settling time, it is important to use multiple bypass capacitors. A 0.1µF ceramic disc in parallel with a 4.7µF tantalum is recommended. Two oscilloscope photos with different bypass conditions are used to illustrate the settling time characteristics of the amplifier.

The best performance can be obtained by double termination (75Ω in series with the output of the amplifier, and 75Ω 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. For a cable driver with a gain of 5 (op amp gain of 10) the – 3dB bandwidth is 56MHz with only 0.25dB of peaking. LT1192 • TA06 SETTLING TIME TO 1mV, AV = –1 SUPPLY BYPASS CAPACITORS = 0.1µF + 4.7µF TANTALUM Cable Terminations The LT1192 operational amplifier has been optimized as a low cost video cable driver. The ±50mA guaranteed output current enables the LT1192 to easily deliver 7.5VP-P into 100Ω, 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 (75Ω to ground) to absorb unwanted 8 Using the Shutdown Feature The LT1192 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 15kΩ 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. When the output is loaded with as little as 1kΩ from the amplifier’s feedback resistors, the amplifier shuts off in 400ns. This shutoff can be under the control of HC CMOS operating between 0V and – 5V. LT1192 U W U U APPLICATIO S I FOR ATIO Small-Signal Transient Response Output Shutdown 0V VSHDN – 5V VOUT LT1192 • TA08 LT1192 • TA09 1MHz SINE WAVE GATED OFF WITH SHUTDOWN PIN, AV = 10, RL = 1k AV = 10, SMALL-SIGNAL RISE TIME, WITH FET PROBES 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 SHDN pin close to the negative supply to keep the supply current from increasing. Closed-Loop Voltage Gain vs Frequency When using decompensated amplifiers it should be realized that peaking in the frequency domain, and overshoot and ringing in the time domain occur as closed-loop gain is lowered. The LT1192 is stable to a closed-loop gain of 5, however, peaking and ringing can be minimized by increasing the closed-loop gain. For instance, the LT1192 peaks 5dB when used in a gain of 5, but peaks by less than 0.5dB for a closed-loop gain of 10. Likewise, the overshoot drops from 50% to 4% for gains of 10. Murphy Circuits There are several precautions the user should take when using the LT1192 in order to realize its full capability. Although the LT1192 can drive a 50pF load, isolating the capacitance with 20Ω can be helpful. Precautions primarily have to do with driving large capacitive loads.

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. 9 LT1192 U W U U APPLICATIO S I FOR ATIO Driving Capacitive Load Driving Capacitive Load LT1192 • TA11 LT1192 • TA12 AV = –5, IN DEMO BOARD, CL = 50pF AV = –5, IN DEMO BOARD, CL = 50pF WITH 20Ω ISOLATING RESISTOR Murphy Circuits 5V 3 + 5V 6 LT1192 2 3 7 – + COAX 7 6 LT1192 2 4 – –5V 4 –5V An Unterminated Cable Is a Large Capacitive Load 1X SCOPE PROBE A 1X Scope Probe Is a Large Capacitive Load 5V 3 + 7 6 LT1192 2 – + LT1192 4 – –5V SCOPE PROBE LT1192 • TA13 A Scope Probe on the Inverting Input Reduces Phase Margin 10 LT1192 Is Stable for Gains ≥ 5V/V LT1192 W W SI PLIFIED SCHE ATIC 7 V+ VBIAS VBIAS CM + 3 – 2 CFF +V 6 VOUT +V * 4 V– LT1191 • TA14 5 1 8 SHDN BAL BAL *SUBSTRATE DIODE, DO NOT FORWARD BIAS U PACKAGE DESCRIPTIO J8 Package 8-Lead CERDIP (Narrow .300 Inch, Hermetic) (Reference LTC DWG # 05-08-1110) CORNER LEADS OPTION (4 PLCS) 0.023 – 0.045 (0.584 – 1.143) HALF LEAD OPTION 0.300 BSC (0.762 BSC) 0.200 (5.080) MAX 0.045 – 0.068 (1.143 – 1.727) FULL LEAD OPTION 0.015 – 0.060 (0.381 – 1.524) 0.008 – 0.018 (0.203 – 0.457) 0.005 (0.127) MIN 0.405 (10.287) MAX 8 7 6 5 0.025 (0.635) RAD TYP 0.220 – 0.310 (5.588 – 7.874) 0° – 15° 1 0.045 – 0.065 (1.143 – 1.651) 0.014 – 0.026 (0.360 – 0.660) 0.100 (2.54) BSC 2 3 4 J8 1298 0.125 3.175 MIN NOTE: LEAD DIMENSIONS APPLY TO SOLDER DIP/PLATE OR TIN PLATE LEADS OBSOLETE PACKAGE Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
