0.56 Ω On Resistance High Density Octal SPST Switch

FEATURES

GENERAL DESCRIPTION

► 0.56 Ω typical on resistance

The ADGS2414D contains eight independent, low on-resistance,

single-pole/single-throw (SPST) switches in a 4 mm x 5 mm, 30 pin

LGA package.

► High continuous current of up to 768 mA

► Flat R_ONacross signal range, 0.004 Ω

► THD of -122 dB at 1 kHz

The ADGS2414D enables higher channel density in systems where

printed circuit board space is constrained or existing system form

factors restrict expansion.

► Route through pins for digital signals and supplies

► Integrated passive components

► SPI interface with error detection

► Guaranteed break-before-make switching, allowing external wir-

ing of switches to deliver multiplexer configurations

► Fully specified at ±15 V and +12 V

► 1.8 V logic compatibility with 2.7 V ≤ V_L≤ 3.3 V (excludes SPI

read-back to a 1.8 V device)

When using SPI daisy-chain mode, the unique route through pins,

provide considerable space savings when multiple ADGS2414D

instances are combined to design very high channel count systems,

such as large switching matrices and fanout applications. The

integrated supply decoupling capacitors and SDO pullup resistor

further increase the space savings and reduce printed circuit board

complexity.

► 4 mm × 5 mm, 30-terminal LGA

The low on-resistance (0.56 Ω typical) of each switch channel

allows for higher current density in systems where heat dissipation

is an issue, and the on-resistance profile of the switch channels is

exceptionally flat over the full-analog input range, which ensures

good linearity and low distortion when switching precision analog

signals.

APPLICATIONS

► Automatic test equipment

► Instrumentation

► Data acquisition

► Relay replacement

► Avionics

► Audio and video switching

► Communication systems

Each switch has an input signal range from V_SSto V_DD– 2 V. When

on, each switch conducts equally well in both directions, and in the

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

The SPI has robust error detection features, such as cyclic redun-

dancy check (CRC) error detection, invalid read and write address

detection, and SCLK count error detection.

PRODUCT HIGHLIGHTS

1. The SPI removes the need for parallel conversion, logic traces,

and reduces the general-purpose input/output (GPIO) channel

count.

2. Daisy-chain mode removes additional logic traces when multi-

ple devices are used.

3. Route through of digital signals and supplies eases routing and

allows for an increase in channel density.

4. Integrated passive components eliminate the need for external

passive components.

5. CRC error detection, invalid read and write address detection,

and SCLK count error detection ensure a robust digital inter-

face.

6. CRC, invalid read and write address, and SCLK error detection

capabilities allow for the use of the ADGS2414D in safety-criti-

cal systems.
