GENERAL DESCRIPTION

The ADG1421/ADG1422/ADG1423 contain two independent

single-pole/single-throw (SPST) switches. The ADG1421 and

ADG1422 differ only in that the digital control logic is inverted.

The ADG1421 switches are turned on with Logic 1 on the

appropriate control input, and Logic 0 is required for the

ADG1422. The ADG1423 has one switch with digital control

logic similar to that of the ADG1421; the logic is inverted on

the other switch. The ADG1423 exhibits break-before-make

switching action for use in multiplexer applications. Each

switch conducts equally well in both directions when on and

has an input signal range that extends to the supplies. In the

off condition, signal levels up to the supplies are blocked.

The on resistance profile is very flat over the full analog input

range ensuring excellent linearity and low distortion when

switching audio signals. The iCMOS construction ensures

ultralow power dissipation, making the part ideally suited for

portable and battery-powered instruments.

The iCMOS® (industrial CMOS) modular manufacturing process

combines high voltage, complementary metal-oxide semiconductor

(CMOS) and bipolar technologies. It enables the development

of a wide range of high performance analog ICs capable of 33 V

operation in a footprint that no other generation of high voltage

parts has achieved. Unlike analog ICs using conventional CMOS

processes, iCMOS components can tolerate high supply voltages

while providing increased performance, dramatically lower

power consumption, and reduced package size.

PRODUCT HIGHLIGHTS

1. 2.4 Ω maximum on resistance at 25°C.

2. Minimum distortion.

3. 3 V logic-compatible digital inputs: V_INH= 2.0 V, V_INL= 0.8 V.

4. No V_Llogic power supply required.

5. 10-lead MSOP and 10-lead, 3 mm × 3 mm LFCSP packages.
