_______________General Description
Maxim’s redesigned DG411/DG412/DG413 analog switches now feature low on-resistance matching between switches (3Ω max) and guaranteed on-resis- tance flatness over the signal range (∆4Ω max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers lower off leakage current over temperature (less than 5nA at +85°C).
The DG411/DG412/DG413 are quad, single-pole/sin- gle-throw (SPST) analog switches. The DG411 is normally closed (NC), and the DG412 is normally open (NO). The DG413 has two NC switches and two NO switches. Switching times are less than 150ns max for tON and less than 100ns max for tOFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim’s improved DG411/DG412/DG413 are fabricated with a 44V silicongate process.

Note 1: Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet.
Note 3: Guaranteed by design.
Note 4: ∆RON = ∆RON max - ∆RON min. On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and minimum value of on resistance as measured at the extremes of the specified analog signal range.
Note 5: Off Isolation = 20 log (VD/VS), VD = output, VS = input to off switch. See Figure 5. Note 6: Between any two switches. See Figure 6.
Note 7: Leakage parameters IS(OFF), ID(OFF), and ID(ON) are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
