The PS320 is improved high-precision, medium voltage analog switches designed to operate with ±3V to ±8V power supplies. The PS320 is a dual, single-pole single-throw (SPST), normally open (NO) switch. When on, each switch conducts current equally well in either direction. In the off state, each switch blocks voltages up to the power-supply rails. With ±5V power supplies, the PS320 guarantee <35ohm ON-resistance. ON-resistance matching between channels is within 2ohm. ON-resistance flatness is less than 4ohm over the specified range. All three devices guarantee low leakage currents (<100pA @25°C, <10nA @+85°C) and fast switching speeds (tON<150ns). Break-before-make switching action protects against momentary crosstalk (PS322). For single-supply operation the PS323/PS324/PS325 are recommended. Low On-Resistance (17ohms typ.) Minimizes Distortion and Error Voltages Low Glitching Reduces Step Errors in Sample-and-Holds Split-Supply Operation (±3V to ±8V) Improved Second Sources for MAX320 On-Resistance Matching Between Channels, 0.2ohm typ On-Resistance Flatness,<2ohm typ Low Off-Channel Leakage, <5nA @ +85°C TTL/CMOS Logic Compatible Fast Switching Speed, tON <150ns Guaranteed Break-Before-Make action (PS322) eliminates momentary crosstalk Rail-to-Rail Analog Signal Dynamic Range Low Power Consumption,<1.25mW Packaging (Pb-free & Green)
