7 / 12 page __________Applications Information Low-Distortion Audio The MAX312/MAX313/MAX314, having very low RON and very low RON variation with signal amplitude, are well suited for low-distortion audio applications. The Typical Operating Characteristics show Total Harmonic Distortion (THD) vs. Frequency graphs for several sig- nal amplitudes and impedances. Higher source and load impedances improve THD, but reduce off isolation. Off Isolation at High Frequencies In 50 Ω systems, the high-frequency on-response of these parts extends from DC to above 100MHz with a typical loss of -2dB. When the switch is turned off, how- ever, it behaves like a capacitor, and off isolation decreases with increasing frequency. (Above 300MHz, the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50 Ω source and load connected with BNC connec- tors to a circuit board deemed “average”; that is, designed with isolation in mind, but not using strip-line or other special RF circuit techniques. For critical appli- cations above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz. 10 Ω, Quad, SPST, CMOS Analog Switches _______________________________________________________________________________________ 7 V+ COM_ V- NO_ Vg V+ V- tr < 20ns tf < 20ns 50% 0V LOGIC INPUT V- -15V RL 300 Ω NO1 OR NC1 GND CL INCLUDES FIXTURE AND STRAY CAPACITANCE.
