A 0.1 µF 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 ampli- fied to 10mV/DIV the settling time to 10mV is 347ns for the 0.1 µF bypass; the time drops to 96ns with multiple bypass capacitors. Operating With Low Closed-Loop Gains The LT1193 has been optimized for closed-loop gains of 2 or greater; the frequency response illustrates the ob- tainable closed-loop bandwidths. For a closed-loop gain of 2 the response peaks about 2dB. Peaking can be minimized by keeping the feedback elements below 1k Ω, and can be eliminated by placing a capacitor across the feedback resistor, (feedback zero). This peaking shows up as time domain overshoot of about 40%. With the feedback capacitor it is eliminated. Cable Terminations The LT1193 video difference amplifier has been optimized as a low cost cable driver. The ±50mA guaranteed output current enables the LT1193 to easily deliver 7.5VP-P into No Supply Bypass Capacitors LT1192 • TA04 AV = 10, IN DEMO BOARD, RL = 1k LT1192 • TA05 SETTLING TIME TO 10mV, AV = 2 SUPPLY BYPASS CAPACITORS = 0.1 µF VOUT 1V/DIV 0V LT1192 • TA06 SETTLING TIME TO 10mV, AV = 2 SUPPLY BYPASS CAPACITORS = 0.1 µF + 4.7µF TANTALUM VOUT 1V/DIV 0V Settling Time Poor Bypass Settling Time Good Bypass 0V 0V VOUT 10mV/DIV VOUT 10mV/DIV |
