GENERAL DESCRIPTION
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.
The ADGS2414D enables higher channel density in systems where
printed circuit board space is constrained or existing system form
factors restrict expansion.
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.
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.
Each switch has an input signal range from VSS to VDD – 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 redundancy
check (CRC) error detection, invalid read and write address
detection, and SCLK count error detection.
