_______________General Description
Maxim’s redesigned DG411/DG412/DG413 analog switches now feature low on-resistance matching between switches (3Ω max) and guaranteed on-resis­tance 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/sin­gle-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 tONand less than 100ns max for t
OFF
. 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.

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.

__________Applications Information
Operation with Supply Voltages
Other Than 15V
Using supply voltages other than 15V will reduce the analog signal range. The DG411/DG412/DG413 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. V
L
must be connected to +5V to be TTL com­patible, or to V+ for CMOS-logic level inputs. The Typical Operating Characteristics graphs show typical on-resistance with ±15V, ±10V, and ±5V supplies. (Switching times increase by a factor of two or more for operation at ±5V.)
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 VL, 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 diodes reduces the analog signal range to 1V below V+ and 1V below V-, without affecting low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V.
