19-4611; Rev 5; 5/09 Improved, Quad, SPST Analog Switches New Features ♦ ♦ ♦ ♦ ♦ Plug-In Upgrades for Industry-Standard DG441/DG442 Improved rDS(ON) Match Between Channels(4Ωmax) Guaranteed rFLAT(ON) Over Signal Range (9Ωmax) Improved Charge Injection (10pC max) Improved Off-Leakage Current Over Temperature (<5nA at +85°C) ♦ Withstand Electrostatic Discharge (2000V min) per Method 3015.7 Maxim’s redesigned DG441/DG442 analog switches now feature on-resistance matching (4Ω max) between switches and guaranteed on-resistance flatness over the signal range (9Ω max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection (10pC max), low power consumption (1.65mW), 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 DG441/DG442 are quad, single-pole/single-throw (SPST) analog switches. The DG441 has four normally closed switches, and the DG442 has four normally open switches. Switching times are less than 250ns for tON and less than 170ns for tOFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim’s improved DG441/DG442 continue to be fabricated with a 44V silicon-gate process.

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: On-resistance match between channels and flatness is guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the specified analog range. Note 5: 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.

(Thin QFN package only.) — — 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 can cause permanent damage to the devices. Always sequence V+ on first, followed by V- and logic inputs. If power-supply sequencing is not possible, add two small, external signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding external diodes reduces the analog-signal range to 1V below V+ and 1V above V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V. V+ Applications Information D S Operation with Supply Voltages Other Than ±15V Using supply voltages other than ±15V reduces the analog signal range. The DG441/DG442 switches operate with ±4.5V to ±20V bipolar supplies or with a +10V to +30V single supply; connect V- to 0V when operating with a single supply. Also, all device types can operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with ±20V, ±15V, ±10V, and ±5V sup- 6 Vg V- Figure 1.
