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.

MAX4521/MAX4522/MAX4523 Quad, Low-Voltage, SPST Analog Switches Applications Information Power-Supply Considerations Overview The MAX4521/MAX4522/MAX4523 construction is typical of most CMOS analog switches. They have three supply pins: V+, V-, and GND. V+ and V- are used to drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between each analog-signal pin and both V+ and V-.
