Quad, Low-Voltage, SPST Analog Switches
General Description
Features
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.
♦ +2V to +12V Single Supply
±2V to ±6V Dual Supplies
♦ 100Ω Signal Paths with ±5V Supplies
♦ Low Power Consumption, <1µW
♦ 4 Separately Controlled SPST Switches
♦ Rail-to-Rail Signal Handling
♦ Pin Compatible with Industry-Standard
DG211/DG212/DG213
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.
Applications
Battery-Operated Equipment
♦ >2kV ESD Protection per Method 3015.7
♦ TTL/CMOS-Compatible Inputs with ±5V or
Single +5V Supply
