General Description

The MAX4599 single-pole/double-throw (SPDT) switch

operates from a +2.0V to +5.5V single supply. It offers

60Ω max on-resistance (R

) at +5V and fast switching

times (t

= 30ns max, t

OFF

= 25ns max).

The MAX4599 features excellent R

flatness (4Ω max)

and matching (1Ω max) between channels. This device

also offers 5pC max charge injection.

The MAX4599 is available in tiny 6-pin SC70, µDFN, and

SOT23 packages.

9-1637; Rev 2; 2/04 Low-Voltage, Single-Supply, SPDT Analog Switch in SC70 The MAX4599 single-pole/double-throw (SPDT) switch operates from a +2.0V to +5.5V single supply. It offers 60Ω max on-resistance (RON) at +5V and fast switching times (tON = 30ns max, tOFF = 25ns max). The MAX4599 features excellent RON flatness (4Ω max) and matching (1Ω max) between channels. This device also offers 5pC max charge injection. The MAX4599 is available in tiny 6-pin SC70, µDFN, and SOT23 packages.
