Charge Injection, 2pC typ • Single-Supply Operation (+2.5V to +16V) • Improved Second Sources for MAX4501/MAX4502 • On-Resistance Matching Between Channels, <2Ω • On-Resistance Flatness, <6Ω max • Low Off-Channel Leakage, <5nA @ +85oC • TTL/CMOS Logic Compatible • Fast Switching Speed, tON < 150ns • Guaranteed Break-Before-Make action (PS303 only) eliminates momentary crosstalk • Rail-to-Rail Analog Signal Dynamic Range • Low Power Consumption, <5µW • MSOP Package minimizes board area Description The PS301/PS302/PS303 are improved high precision, medium voltage analog switches designed to operate with single power supplies. The PS301 is a single-pole single-throw (SPST), normally open (NO) switch. The PS302 has the same pinout as the PS301 but is a normally closed (NC) switch. The PS303 has one normally open (NO) and one normally closed (NC) switch per package. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power-supply rail. With a +5V power supply, the PS301/PS302/PS303 guarantee <60Ω ON-resistance. ON-resistance matching between channels is within 2Ω. ON-resistance flatness is less than 6Ω over the specified range. All three devices guarantee low leakage currents (<100pA @ 25oC, <10nA @ +85oC) and fast switching speeds (tON < 150ns). Break-before-make switching action protects against momentary crosstalk (PS303). For single-supply operation below 5V, the PI5A317/318/319 are also recommended.
