LT1190 Ultrahigh Speed Operational Amplifier FEATURES s s s s s s s s s s DESCRIPTIO Gain Bandwidth Product, AV = 1: 50MHz Slew Rate: 450V/µs Low Cost Output Current: ± 50mA Settling Time: 140ns to 0.1% Differential Gain Error: 0.1%, (RL = 1k) Differential Phase Error: 0.06°, (RL = 1k) High Open-Loop Gain: 10V/mV Min Single Supply 5V Operation Output Shutdown The LT®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. , LTC and LT are registered trademarks of Linear Technology Corporation.

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 = 1kΩ. No Supply Bypass Capacitors LT1190 • TA04 AV = – 1, IN DEMO BOARD, RL = 1kΩ 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.

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 1mV/DIV the settling time to 2mV is 4.244µs for the 0.1µF bypass; the time drops to 163ns with multiple bypass capacitors.

The ± 50mA guaranteed output current enables the LT1190 to easily deliver 7.5VP-P into 100Ω, while operating on ± 5V supplies or 2.6VP-P on a single 5V supply.

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. 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 150Ω 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 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. 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 1kΩ the amplifier shuts off in 400ns. This shutoff can be under the control of HC CMOS operating between 0V and – 5V.

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 10Ω 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. (For instance, closed-loop gain of 2 can use RFB = 300Ω and RG = 300Ω.)
