U U W U APPLICATIO S I FOR ATIO Power Supply Bypassing No Supply Bypass Capacitors
The LT1192 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. A scope photo of the amplifier output with no supply by- passing 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 LT1192 • TA04 bypass conditions are used to illustrate the settling time AV = – 5, IN DEMO BOARD, RL = 1k characteristics of the amplifier. Note that although the output waveform looks acceptable at 1V/DIV, when 7
