The MAX381/MAX383/MAX385 are precision, low-volt-
a g e a na log s witc he s . The s ing le -p ole s ing le -throw
MAX381 and double-pole single-throw MAX385 dual
switches are normally open. The single-pole double-
throw MAX383 has two normally open and two normally
closed poles. All three parts offer low on-resistance
(le s s tha n 35Ω), g ua ra nte e d to ma tc h to within 2Ω
between channels and to remain flat over the specified
analog signal range (4Ω max). They also offer low leak-
age (less than 250pA at +25°C and less than 2.5nA at
+85°C) and fast switching (turn-on time less than 175ns
and turn-off time less than 100ns).
♦ Single-Supply Operation (+3V to +15V)
Bipolar-Supply Operation (±3V to ±8V)
♦ Pin-Compatible with DG401/DG403/DG405
♦ Low On-Resistance, 20Ω Typical (35Ω Max)
♦ Guaranteed Matched On-Resistance Between
Channels, <2Ω
♦ Guaranteed Flat On-Resistance over Specified
Analog Signal Range, <4Ω
♦ Guaranteed Charge Injection, <5pC
♦ Guaranteed Off-Channel Leakage, <2.5nA at +85°C
The MAX381/MAX383/MAX385 a re fa b ric a te d with
Maxim’s low-voltage silicon-gate process for high sys-
te m a c c ura c y. De s ig n imp rove me nts g ua ra nte e
extremely low charge injection (<5pC) and low power
consumption (<10µW).
♦ TTL/CMOS-Logic Compatible with 3V, 5V, ±3V,
and ±5V Supplies
♦ Rail-to-Rail Analog Signal Handling Capability
______________Ord e rin g In fo rm a t io n
These monolithic switches operate with a single posi-
tive supply (+3V to +15V) or with split supplies (±3V to
±8V) while retaining CMOS-logic input compatibility
and fast switching. CMOS inputs provide reduced input
loading.

Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to
maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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.

Note 2: 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: ∆R

specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as
measured over the specified analog signal range.

The MAX381/MAX383/MAX385 switches operate with
±3.0V to ±8V bipolar supplies and a +3V to +15V single
supply. In either case, analog signals ranging from V+ to
V- can be switched. The Typical Operating Characteristics
graphs show the typical on-resistance variation with ana-
log signal and supply voltage. The usual on-resistance
temperature coefficient is 0.5%/°C (typ).

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 can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
s e rie s with s up p ly p ins for ove rvolta g e p rote c tion
(Figure 1). Adding diodes reduces the analog signal
range to one diode drop below V+ and one diode drop
above V-, but does not affect the devices’ low switch
resistance and low leakage characteristics. Device
operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection
diodes are not recommended when using a single 3V
supply.
