19-0420; Rev 1; 6/99 10Ω, Quad, SPST, CMOS Analog Switches Maxim’s MAX312/MAX313/MAX314 analog switches feature low on-resistance (10Ω max) and 1.5Ω on-resistance matching between channels. These switches conduct equally well in either direction. They offer low leakage over temperature (2.5nA at +85°C). Low power consumption and ESD tolerance greater than 2000V per Method 3015.7 are guaranteed. The MAX312/MAX313/MAX314 are quad, singlepole/single-throw (SPST) analog switches. The MAX312 is normally closed (NC), and the MAX313 is normally open (NO). The MAX314 has two NC switches and two NO switches. All three devices operate from a single supply of +4.5V to +30V or from dual supplies of ±4.5V to ±20V. ________________________Applications ____________________________Features ♦ Pin Compatible with DG411/DG412/DG413 ♦ Low On-Resistance (6.5Ω typical) ♦ Guaranteed RON Match Between Channels (1.5Ω max) ♦ Guaranteed RON Flatness over Specified Signal Range (2Ω max) ♦ Guaranteed ESD Protection > 2000V per Method 3015.7 ♦ Crosstalk > 96dB at 20kHz ♦ Single-Supply Operation: +4.5V to +30V Dual-Supply Operation: ±4.5V to ±20V ♦ Rail-to-Rail Signal Handling ______________Ordering Information PART TEMP.

The Typical Operating Characteristics show Total Harmonic Distortion (THD) vs. Frequency graphs for several signal amplitudes and impedances. Higher source and load impedances improve THD, but reduce off isolation. 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 applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz. V+ Off Isolation at High Frequencies In 50Ω 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, however, 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 50Ω source and load connected with BNC connec- V+ NO_ COM_ Vg V- V- Figure 1.
