GENERAL DESCRIPTION
The ADG726/ADG732 are monolithic CMOS 32-channel/dual
16-channel analog multiplexers. The ADG732 switches one of
32 inputs (S1-S32) to a common output, D, as determined by
the 5-bit binary address lines A0, A1, A2, A3, and A4. The
ADG726 switches one of 16 inputs as determined by the 4-bit
binary address lines A0, A1, A2, and A3.
On-chip latches facilitate microprocessor interfacing. The
ADG726 device may also be configured for differential opera-
tion by tying CSA and CSB together. An EN input is used to
enable or disable the devices. When disabled, all channels are
switched OFF.
These multiplexers are designed on an enhanced submicron
process that provides low power dissipation yet gives high
switching speed, very low on resistance, and leakage currents.
They operate from a single supply of +1.8 V to +5.5 V and a ± 2.5 V
dual supply, making them ideally suited to a variety of applications.
On resistance is in the region of a few ohms and is closely
matched between switches and very flat over the full signal
range. These parts can operate equally well as either multiplexers
or demultiplexers and have an input signal range that extends to
the supplies. In the OFF condition, signal levels up to the supplies
are blocked. All channels exhibit break-before-make switching
action, preventing momentary shorting when switching channels.
They are available in either 48-lead CSP or TQFP packages.
