Analog Devices ADG1534 Product Info

The ADG1534 contains four independent SPDT switches. An EN input on the ADG1534 is used to enable or disable the device. When disabled, all channels are high impedance. The digital inputs, INx, are 1.8 V logic-compatible and suitable for low voltage logic controls.

The ADG1534 is fully specified at V_DD = +5 V ± 10% and V_SS = −4.5 V to −8.8 V for applications that require asymmetrical supplies. The ultra-low on resistance and on-resistance flatness of the switches makes it an ideal solution for data acquisition and gain switching applications, where low distortion is critical. The construction ensures ultra-low power dissipation, making the device ideally-suited for portable and battery-powered instruments.

The switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All channels exhibit a break-before-make switching action that prevents momentary shorting when switching channels.
