Improved, Dual, High-Speed Analog Switches
_______________General DescriptionMaxim's redesigned DG401/DG403/DG405 analog
switches now feature guaranteed low on-resistance
matching between switches (2Ωmax) and guaranteed
on-resistance flatness over the signal range (3Ωmax).
These low on-resistance switches (20Ωtyp) 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 +85°C).
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 tONand
100ns max for tOFF, with a maximum power consump-
tion of 35μW. These devices operate from a single
+10V to +30V supply, or bipolar supplies of ±4.5V to20V. Maxim's improved DG401/DG403/DG405 are
fabricated with a 44V silicon-gate process.

maximum.
Note 3:Guaranteed by design.
Note 4:ΔrON= ΔrON(max) - ΔrON(min). On-resistance match between channels and flatness are guaranteed only with specified
voltages. 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.

mproved, Dual, High-Speed Analog Switches__________Applications Information_____________________Pin DescriptionFigure 1. Overvoltage Protection Using External Blocking Diodes
Operation with Supply Voltages her than ±15VThe 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
Characteristicsgraphs illustrate typical analog-signal
and supply-voltage on-resistance variations. The usual
on-resistance temperature coefficient is 0.5%/°C (typ).
Logic InputsThese 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 VLis connected to V+ or another
supply at voltages other than +5V, the devices will
operate at CMOS-logic-level inputs.
Overvoltage ProtectionProper 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 affect-
ing low switch resistance and low leakage
characteristics. Device operation is unchanged, and
the difference between V+ and V- should not exceed
+44V.
