PS321 Overview
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.
PS321 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, <2Ω typ
- Low Off-Channel Leakage, <5nA @ +85°C
- TTL/CMOS Logic patible
- Fast Switching Speed, tON <150ns
- Guaranteed Break-Before-Make action (PS322) eliminates momentary crosstalk
