General Description

The MAX4591/MAX4592/MAX4593 are high-speed,

precision, quad, single-pole/single-throw (SPST) analog

switches designed to operate at +12V or +15V. The

MAX4591 has four normally closed (NC) switches, and

the MAX4592 has four normally open (NO) switches.

The MAX4593 has two NO and two NC switches. All

three devices offer low leakage (100pA max) and fast

switching speeds (t

≤ 80ns, t

OFF

≤ 45ns).

With a +12V supply, the MAX4591/MAX4592/MAX4593

offer guaranteed 1Ω max channel-to-channel matching,

20Ω max on-resistance (R

), and 1.75Ω max R

flat-

ness over the specified range.

These switches are also fully specified for single +15V

operation, with 16Ω max R

ON,

1.5Ω max R

match,

and 1.5Ω max flatness. For low-voltage or dual-supply

operation, refer to the MAX391 data sheet.

These low-voltage switches also offer 5pC max charge

injection, and electrostatic discharge (ESD) protection

is greater than 2000V, per Method 3015.7.
