ADI's ADG1634L is a monolithic industrial CMOS (iCMO) analog switch containing four independently selectable single-pole, double-throw (SPDT) switches. Each switch has an input signal range that extends to the power supply, and each switch has equally good continuity in both directions when turned on. In a disconnected condition, a signal level equal to the power supply is blocked.
All channels have break-before-make switching function, which can prevent short-circuit phenomenon when switching channels. The EN input on the ADG1634L enables or disables the device. The switch is enabled by a logic 1 EN input; the INx input defines the state of the SPDT switch (see Table 12 in the data sheet). When the EN input is disabled, all channels are turned off.
The ultra-low on-resistance and on-resistance flatness of the switches are ideal where low distortion is critical for data acquisition and gain switching applications. Due to its iCMOS structure ensuring ultra-low power consumption, the device is ideal for portable and battery-operated instruments.
An external VL supply provides flexibility for lower logic control. The ADG1634L is 1.2 V and 1.8 V JEDEC compliant. The EVAL-ADG1634LEBZ is an evaluation board for the ADG1634L.
