GENERAL DESCRIPTION
The ADG658 and ADG659 are low voltage, CMOS analog
multiplexers comprised of eight single channels and four
differential channels, respectively. The ADG658 switches one of
eight inputs (S1–S8) to a common output, D, as determined by
the 3-bit binary address lines A0, A1, and A2. The ADG659
switches one of four differential inputs to a common differential
output, as determined by the 2-bit binary address lines A0 and
A1. An EN input on both devices is used to enable or disable
the device. When disabled, all channels are switched off.
These parts are designed on an enhanced process that provides
lower power dissipation yet gives high switching speeds. These parts
can operate equally well as either multiplexers or demultiplexers
and have an input range that extends to the supplies. All
channels exhibit break-before-make switching action, preventing
momentary shorting when switching channels. All digital inputs
have 0.8 V to 2.4 V logic thresholds, ensuring TTL/CMOS logic
compatibility when using single +5 V or dual ±5 V supplies.
The ADG658 and ADG659 are available in 16-lead TSSOP/
QSOP packages and 16-lead 4 mm × 4 mm LFCSP packages.
PRODUCT HIGHLIGHTS
