MAXIM DG444, DG445 User Manual

General Description

Maxim’s redesigned DG444/DG445 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 (35µW max), and an electrostatic dis­charge (ESD) tolerance of 2000V (min) per Method

3015.7. The new design offers lower off-leakage current
over temperature (less than 5nA at +85°C).

The DG444/DG445 are quad, single-pole/single-throw
(SPST) analog switches. The DG444 has four normally
closed switches and the DG445 has four normally open
switches. Switching times are less than 250ns for t

ON

and less than 70ns for t

OFF

. Operation is from a single
+10V to +30V supply, or bipolar ±4.5V to ±20V sup­plies. Maxim’s improved DG444/DG445 continue to be
fabricated with a 44V silicon-gate process.

Note 2: Typical values are for design aid only, are not guaranteed, and are not subject to production testing. The algebraic convention,

Note 3: Guaranteed by design.
Note 4: On-resistance match between channels and flatness are 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 signal range.

Applications Information

General Operation

• Switches are open when power is off.

• IN, D, and S should not exceed V+ or V-, even with
the power off.

• Switch leakage is from each analog switch terminal
to V+ or V-, not to other switch terminals.

Operation with Supply Voltages

Other than ±15V

Using supply voltages other than ±15V will reduce the
analog signal range. The DG444/DG445 switches oper-

ate 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
±20V, ±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 above
V-, but low switch resistance and low leakage char­acteristics are unaffected. Device operation is
unchanged, and the difference between V+ and V­should not exceed +44V.
