Description

The PS320/PS321/PS322 are improved high-precision, medium volt-

age 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. The PS321 has the same pinout as the

PS320 but it has two normally closed (NC) switches. The PS322 has

one normally open (NO) and one normally closed (NC) switch per

package. 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/PS321/PS322 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 (t

<150ns). Break-before-make switching action protects against

momentary crosstalk (PS322).

For single-supply operation the PS323/PS324/PS325 are recom-

mended.
