♦ Plug-In Upgrades for Industry-Standard

Maxim’s redesigned DG417/DG418/DG419 precision,

CMOS, monolithic analog switches now feature guar-

a nte e d on-re s is ta nc e ma tc hing (3Ω ma x) b e twe e n

switches and guaranteed on-resistance flatness over

the signal range (4Ω max). These switches conduct

e q ua lly we ll in e ithe r d ire c tion a nd g ua ra nte e low

charge injection, low power consumption, and an ESD

tolerance of 2000V minimum per Method 3015.7. The

new design offers low off-leakage current over temper-

ature (less than 5nA at +85°C).

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

Ot h e r t h a n ±1 5 V

Using supply voltages other than ±15V reduces the

analog signal range. The DG417/DG418/DG419 switch-

es 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. VL must be connected to +5V to be TTL com-

p a tib le , or to V+ for CMOS-log ic le ve l inp uts . The

Typical Operating Characteristics graphs show typical

on-resistance with ±20V, ±15V, ±10V, and ±5V sup-

plies. (Switching times increase by a factor of two or

more for operation at ±5V.)

DG41_

V-

Ove rvo lt a g e P ro t e c t io n

Proper power-supply sequencing is recommended for

all CMOS devices. Do not exceed the absolute maxi-

mum ratings because stresses beyond the listed rat-

ings 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 possi-

ble, add two small, external signal diodes in series with

the supply pins for overvoltage protection (Figure 1).

Figure 1. Overvoltage Protection Using External Blocking Diodes

Adding diodes reduces the analog signal range to 1V

below V+ and 1V above 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.
