Quad, Low-Voltage, SPST Analog Switches
_______________General Description
The MAX4521/MAX4522/MAX4523 are quad, low-volt-
age, single-pole/single-throw (SPST) analog switches.
On-resistance (100Ω max) is matched between switch-
es to 4Ω max, and is flat (12Ω max) over the specified
signal range. Each switch can handle rail-to-rail analog
signals. The off-leakage current is only 1nA at +25°C
and 10nA at +85°C.
The MAX4521 has four normally closed (NC) switches,
and the MAX4522 has four normally open (NO) switch-
es. The MAX4523 has two NC switches and two NO
switches.
These CMOS switches can operate with dual power
supplies ranging from ±2V to ±6V or a single supply
between +2V and +12V. They are fully specified for sin-
gle +2.7V operation.
All digital inputs have +0.8V and +2.4V logic thresh-
olds, ensuring TTL/CMOS-logic compatibility when
using ±5V or a single +5V supply.

Note 3: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 4: Guaranteed by design.
Note 5: ∆RON = ∆RON(MAX) - ∆RON(MIN).
Note 6: Resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Note 7: Leakage parameters are 100% tested at maximum rated temperature, and guaranteed by correlation at TA = +25°C.
Note 8: Off-isolation = 20log10 [ VCOM_ / (VNC_ or VNO_) ], VCOM_ = output, VNC_ or VNO_ = input to off switch.
Note 9: Between any two switches.
Note 10: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
