The ADG1633 and ADG1634 are monolithic industrial CMOS
S2A S3A
(iCMOS®) analog switches comprising three independently selectable single-pole, double-throw (SPDT) switches and 002
SWITCHES SHOWN FOR
four independently selectable SPDT switches, respectively.
A 1 INPUT LOGIC.
08319- All channels exhibit break-before-make switching action that Figure 2. ADG1634 TSSOP prevents momentary shorting when switching channels. An EN input on the ADG1633 (LFCSP and TSSOP packages) and ADG1634 (LFCSP package only) is used to enable or disable
ADG1634 S1A S4A
the devices. When disabled, all channels are switched off.
D1 D4
The ultralow on resistance and on-resistance flatness of these
S1B S4B
switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. iCMOS
S2B S3B D2 D3
construction ensures ultralow power dissipation, making the parts
S2A S3A
ideally suited for portable and battery-powered instruments.
