Description

The AS1751/AS1752/AS1753 are high-speed, low-voltage, quad single-pole/single-throw (SPST) analog switches.

Fast switching speeds, low ON-resistance, and low power consumption make these devices ideal for singlecell battery powered applications.

These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches:

• AS1751 - Four normally open (NO) switches
• AS1752 - Four normally closed (NC) switches
• AS1753 - Two NO switches and Two NC switches

The AS1753 supports break-before-make switching.
With very low ON-resistance (RON), RON matching and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks.

The AS1751/AS1752/AS1753 digital logic input is 1.8V CMOS-compatible when using a +3V supply, and all devices can handle Rail-to-Rail signals.

The devices are available in a 3mm x 3mm 16-pin QFN package and a 14-pin TSSOP package.
