Precision, Dual, High-Speed Analog Switches
General Description
The MAX301/MAX303/MAX305 are precision, dual, high-
speed analog switches. The single-pole single-throw
(SPST) MAX301 and double-pole single-throw (DPST)
MAX305 dualswitches are normally open (NO). The sin-
gle-pole double-throw (SPDT) MAX303 has two NO and
two normally closed (NC) poles. All three parts offer low
on resistance (less than 35Ω), guaranteed to match to
within 2Ωbetween channels and to remain flat over the
full analog signal range (Δ3max). They also offer low leak-
age (less than 250pA at +25°C and less than 6nA at
+85°C) and fast switching (turn-on time less than 150ns
and turn-off time less than 100ns).
The MAX301/MAX303/MAX305 are fabricated with
Maxim’s new improved silicon-gate process for high
system accuracy. Design improvements guarantee
extremely low charge injection (15pC) and low power
consumption (35µW). A 44V maximum breakdown volt-
age allows rail-to-rail analog signal capability.
These monolithic switches operate with a single positive
supply (+10V to +30V) or with split supplies (±4.5V
to ±20V) while retaining CMOS-logic input compatibility
and fast switching. CMOS inputs provide reduced input
loading.

Operation with Supply Voltages
Other than ±15V
The MAX301/MAX303/MAX305 switches operate with
±4.5V to ±20V bipolar supplies and a +10V to +30V sin-
gle supply. In either case, analog signals ranging from V+
to V- can be switched. The Typical Operating
Characteristicsgraphs show the typical on-resistance
variation with analog signal and supply voltage. The usual
on-resistance temperature coefficent is 0.5%/°C (typ).
Logic Inputs
The MAX301/MAX303/MAX305 operate with a single pos-
itive supply or with bipolar supplies. The devices 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 Protection
Proper power-supply sequencing is recommended for all
CMOS devices. It is important not to exceed the absolute
maximum 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 possible,
add two small signal diodes in series with the supply pins
for overvoltage protection (Figure 1). Adding diodes
reduces the analog signal range to 1V below V+ and 1V
below V-, but low switch resistance and low leakage char-
acteristics are unaffected. Device operation is
unchanged, and the difference between V+ to V- should
not exceed +44V.
