GENERAL DESCRIPTION
and have an input signal range which extends to the sup-
plies. 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.
The ADG726/ADG732 are monolithic CMOS 32
channel/dual 16 channel analog multiplexers. The
ADG732 switches one of thirty-two 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 sixteen inputs as determined by the four
bit binary address lines, A0, A1, A2 and A3.
They are available in either 48 lead LFCSP or TQFP
package.
On chip latches facilitate microprocessor interfacing. The
ADG726 device may also be configured for differential
operation by tying CSA and CSB together. An EN input
is used to enable or disable the devices. When disabled, all
channels are switched OFF.
PRODUCT HIGHLIGHTS
1. +1.8 V to +5.5 V Single or 2.5 V Dual Supply
operation. These parts are specified and guaranteed
with +5 V 10ꢀ, +3 V 10ꢀ single supply and
2.5 V 10ꢀ dual supply rails.
These multiplexers are designed on an enhanced submi-
cron process that provides low power dissipation yet gives
high switching speed, very low on resistance and leakage
currents. They operate from single supply of 1.8V to 5.5V
and 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 De-Multiplexers
2. On Resistance of 3.5 Ω.
3. Guaranteed Break-Before-Make Switching Action.
4. 7mm x 7mm 48 lead LF Chip Scale Package (CSP)
or 48 lead TQFP package.
