General Description

Maxim’s MAX312/MAX313/MAX314 analog switches

feature low on-resistance (10Ω max) and 1.5Ω on-resis-

tance matching between channels. These switches con-

duct 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, single-

pole/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.

10Ω, Quad, SPST, CMOS Analog Switches 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 signal amplitudes and impedances. Higher source and load impedances improve THD, but reduce off isolation.
