Note 2: A heat sink is required to keep the junction temperature below absolute maximum when the output is shorted. Note 3: There are two limitations on signal swing. Output swing is limited by clipping or saturation in the output stage. Input swing is controlled by an adjustable input limiting function. On VS = ±5V, the overload characteristic is output limiting, but on ±8V the overload characteristic is input limiting. VOMAX is measured with the null pins open circuit. Note 4: Output amplitude is reduced by the input limiting function. The input limiting function occurs when the null pins, 1 and 8, are tied together and raised to a potential 0.3V or more above the negative supply. Note 5: Slew rate is measured between ± 1V on the output, with a ±0.3V input step. Note 6: Full-power bandwidth is calculated from the slew rate measurement: FPBW = SR/2πVP. Note 7: Settling time measurement techniques are shown in “Take the Guesswork Out of Settling Time Measurements,” EDN, September 19, 1985. Note 8: NTSC (3.58MHz). 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 part (S suffix).

The amplifier has two uncommitted high input impedance (+) and (–) inputs that can be used either differentially or single-ended. The LT1194 includes a limiting feature that allows the amplifier to reduce its output as a function of DC voltage on the BAL/VC pins. The limiting feature uses input differential-pair limiting to prevent overload in subsequent stages. This technique allows extremely fast limiting action. Power Supply Bypassing The LT1194 is quite tolerant of power supply bypassing. In some applications a 0.1µF ceramic disc capacitor placed 1/2 inch from the amplifier is all that is required.

In many 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. Note that although the output waveform looks acceptable at 1V/DIV, when amplified to 10mV/DIV the settling time to 10mV is 200ns. The time drops to 162ns with multiple bypass capacitors, and does not exhibit the characteristic power supply ringing.

The ±50mA guaranteed output current enables the LT1194 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 energy. 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 (LT1194 gain of 10), the –3dB bandwidth is over 30MHz with no peaking. A Voltage Controlled Current Source The LT1194 can be used to make a fast, precise, voltage controlled current source. The LT1194 high speed differential amplifier senses the current delivered to the load.

In steady state the input signal appears at the output of the LT1194, and 1/10 of this signal is applied across the sense resistor. Thus the output current is simply: IO = VIN R • 10 The compensation capacitor CC forces the LT1191 to be the dominate pole for the loop, while the LT1194 is fast enough to be transparent in the feedback path. The ratio of the load resistor to the sense resistor should be approximately 10:1 or greater for easy compensation. For the example shown the load resistor is 100Ω, the sense resistor is 5.1Ω, and various loop compensation capacitors cause the output to exhibit an underdamped, critically and overdamped response.

Although the LT1194 can drive a 50pF capacitive load, isolating the capacitance with 10Ω can be helpful. Precautions primarily have to do with driving large capacitive loads.
