ADGS6414D中文资料0.56Ω On Resistance High Density Octal SPST Switch数据手册ADI规格书

描述 Description

The ADGS6414D contains eight independent, low on-resistance,single-pole/single-throw (SPST) switches in a 4mm × 5mm, 30-terminalLGA package.
The ADGS6414D enables higher channel density in systems whereprinted circuit board space is constrained or existing system formfactors restrict expansion.
When using SPI daisy-chain mode, the unique route through pinsprovide considerable space savings when multiple ADGS6414Dinstances are combined to design very high channel count systems,such as large switching matrices and fanout applications. Theintegrated supply decoupling capacitors and SDO pullup resistorfurther increase the space savings and reduce printed circuit boardcomplexity.
The low on-resistance (0.56Ω typical) of each switch channel allowsfor higher current density in systems where heat dissipation isan issue, and the on-resistance profile of the switch channels isexceptionally flat over the full-analog input range, which ensuresgood linearity and low distortion when switching precision analogsignals.
Each switch has an input signal range from VSS to VDD – 2V. Whenon, each switch conducts equally well in both directions, and in theoff condition, signal levels up to the supplies are blocked.
The SPI has robust error detection features, such as cyclic redundancycheck (CRC) error detection, invalid read and write addressdetection, and SCLK count error detection.
PRODUCT HIGHLIGHTSThe SPI removes the need for parallel conversion, logic traces,and reduces the general-purpose input/output (GPIO) channel count.Daisy-chain mode removes additional logic traces when multipledevices are used.Route through of digital signals and supplies eases routing andallows for an increase in channel density.Integrated passive components eliminate the need for externalpassive components.CRC error detection, invalid read and write address detection,and SCLK count error detection ensure a robust digital interface.CRC, invalid read and write address, and SCLK error detectioncapabilities allow for the use of the ADGS6414D in safety-criticalsystems.Pin for pin replacement for the ADGS1414D and ADGS2414D.
