19-4727; Rev 2; 6/99 Improved, Dual, High-Speed Analog Switches ______________________New Features Maxim's redesigned DG401/DG403/DG405 analog switches now feature guaranteed low on-resistance matching between switches (2 max) and guaranteed on-resistance flatness over the signal range (3 max). These low on-resistance switches (20 typ) conduct equally well in either direction and are guaranteed to have low charge injection (15pC max). The new design offers lower off leakage current over temperature (less than 5nA at +85C). The DG401/DG403/DG405 are dual, high-speed switches. The single-pole/single-throw DG401 and double-pole/single-throw DG405 are normally open dual switches. The dual, single-pole/double-throw DG403 has two normally open and two normally closed switches. Switching times are 150ns max for tON and 100ns max for tOFF, with a maximum power consumption of 35W. These devices operate from a single +10V to +30V supply, or bipolar supplies of 4.5V to 20V. Maxim's improved DG401/DG403/DG405 are fabricated with a 44V silicon-gate process.

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.

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. V+ Drain (Analog Signal) Positive Supply-Voltage Input--connected to substrate 14 Logic Inputs These devices operate with a single positive supply or with bipolar supplies. They maintain TTL compatibility with supplies anywhere in the 4.5V to 20V range as long as VL = +5V. If VL is connected to V+ or another supply at voltages other than +5V, the devices will operate at CMOS-logic-level inputs. FUNCTION DIP/SO 11 The DG401/DG403/DG405 switches operate with 4.5V to 20V bipolar supplies or with a +10V to +30V single supply. In either case, analog signals ranging from V+ to V- can be switched. The Typical Operating Characteristics graphs illustrate typical analog-signal and supply-voltage on-resistance variations. The usual on-resistance temperature coefficient is 0.5%/C (typ).
