PS391/PS392/PS393
Precision, Quad, SPST, Analog Switches
Features
Description
• Low On-Resistance, (16−ohms typ)
MinimizesDistortionandErrorVoltages
• On-Resistance Match Between Channels, <2 ohms
• Guaranteed On-Resistance Flatness, <4 ohms
• Low Charge Injection, 3pC typ.
ThePS391/PS392/PS393areimproved,quad,single-polesingle-
throw(SPST)analogswitchesdesigned tooperatewith±3Vto±8V
power supplies or a single 3V to 15V supply. The PS391 has four
normallyclosed(NC)switches, thePS392hasfournormallyopen
(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).Powerconsumptionislessthan1µA,idealfor
battery-powered equipment.
• ImprovedLeakageOverTemperature,<2.5nAat+85oC
• ESDRating>2000VperMethod3015.7
• Single-SupplyOperation(+3Vto+15V)
• Bipolar-SupplyOperation(±3Vto±8V)
• LowPowerConsumption, <1µA
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.
• TTL/CMOSCompatible
Applications
These switches are fully specified for single +5V operation, with
<2ohmRON match,<45ohmRON,and<4ohmflatness.

Applications
As illustrated in Figure 8, PS391 can be used to insert various
capacitors (C1, C2) and set proper RC times for integration. The
resistorsR1andR2setinitialgain.TheRIN resistor xC1orC2sets
the RC time. The reset switch discharges the hold capacitor
through RIN.

Overvoltage Protection
Ordering Information
Proper power-supply sequencing is recommended for all CMOS
devices. Do not exceed the absolute maximum ratings, because
stresses beyond the listed ratings may cause permanent damage
to the devices. Always sequence V+ on first, followed by V-, and
then the logic inputs. If power-supply sequencing is not possible,
add two small signal diodes or two current limiting resistors in
series with the supply pins for overvoltage protection (Figure 9).
Adding diodes reduces the analog signal range, but low switch
resistance and low leakage characteristics are unaffected.
