General Description

The PS320/PS321/PS322 are 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.

The PS321 has the same pinout as the PS320 but it has two normally closed (NC) switches.

Key Features

  • Low On-Resistance (17W 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/MAX321/MAX322.
  • On-Resistance Matching Between Channels, 0.2Ω typ.
  • On-Resistance Flatness,.
