Data Sheet

AS1751 , AS1752, AS1753

High-Speed, Low-Voltage, Single-Supply,

0.9Ω, Quad SPST Analog Switches

1 General Description

2 Key Features

ꢀ

ON-Resistance:

The AS1751/AS1752/AS1753 are high-speed, low-volt-

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

switches.

- 0.9Ω (+3V supply)

- 2.5Ω (+1.8V supply)

Fast switching speeds, low ON-resistance, and low

power consumption make these devices ideal for single-

cell battery powered applications.

RON Matching:

- 0.12Ω (+3V supply)

- 0.25Ω (+1.8V supply)

These highly-reliable devices operate from a single +1.6

to +3.6V supply, and are differentiated by the type and

number of switches:

ꢀ

RON Flatness: 0.1Ω (+3V Supply)

Supply Voltage Range: +1.6 to +3.6V

Switching Speed: tON = 22ns, tOFF = 14ns

Current-Handling: 250mA Continuous

Break-Before-Make Switching (AS1753)

Rail-to-Rail Signal Handling

ꢀ AS1751 – Four normally open (NO) switches

ꢀ AS1752 – Four normally closed (NC) switches

ꢀ AS1753 – Two NO switches and Two NC switches

1.8V CMOS Logic Compatible (+3V Supply)

Operating Temperature Range: -40 to +85ºC

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.

Package Types:

- 16-pin QFN (3mm x 3mm)

- 14-pin TSSOP

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.

3 Applications

The devices are ideal for use in power routing systems,

cordless and mobile phones, MP3 players, CD and DVD

players, PDAs, handheld computers, digital cameras,

hard drives, and any other application where high-speed

signal switching is required.

The devices are available in a 3mm x 3mm 16-pin QFN

package and a 14-pin TSSOP package.
