PS391/PS392/PS393
Precision, Quad, SPST, Analog Switches
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, <1A * TTL/CMOS Compatible
Description
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 1A, 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. These switches are fully specified for single +5V operation, with <2ohm RON match, <45ohm RON, and <4ohm flatness. For operation below 5V, the PI5A391A/PI5A392A/PI5A393A are also recommended.

Applications
As illustrated in Figure 8, PS391 can be used to insert various capacitors (C1, C2) and set proper RC times for integration. The resistors R1 and R2 set initial gain. The RIN resistor x C1 or C2 sets the RC time. The reset switch discharges the hold capacitor through RIN.

Overvoltage Protection
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.
