Precision, Quad, SPST, Analog Switches
Description
Features
• Low On-Resistance, (16−ohms typ)
Minimizes Distortion and Error Voltages
• On-Resistance Match Between Channels, <2 ohms
• Guaranteed On-Resistance Flatness, <4 ohms
• Low Charge Injection, 3pC typ.
• Improved Leakage Over Temperature, <2.5nA at +85oC
• ESD Rating >2000V per Method 3015.7
• Single-Supply Operation (+3V to +15V)
• Bipolar-Supply Operation (±3V to ±8V)
• Low Power Consumption, <1µA
• TTL/CMOS Compatible
The PS391/ PS392/ PS393 are improved, quad, single-pole singlethrow (SPST) analog switches designed to operate with ±3V to ±8V
power supplies or a single 3V to 15V supply. The PS391 has four
normally closed (NC) switches, the PS392 has four normally open
(NO) switches. The PS393 has two NO and two NC switches. All
three devices offer low leakage (<2pA typ) and fast switching
speeds (tON <130ns). Power consumption is less than 1µA, ideal for
battery-powered equipment.
With ±5V supplies, the PS391/PS392/PS393 guarantee <2ohm
channel-to-channel matching, <30ohm on-resistance (RON), and
<4ohm RON flatness over the specified range.
Applications
