Analog Devices Inc. ADG1534 1.8V Logic-Compatible Quad SPDT Switch contains four independent SPDT switches in a small 4mm2 LFCSP-20 package. An EN input on the ADG1534 enables or disables the device. When disabled, all channels are high impedance. The digital inputs (INx) are 1.8V logic-compatible and suitable for low-voltage logic controls. The ADG1534 is fully specified at VDD = +5V ±10% and VSS = -4.5V to -8.8V for applications that require asymmetrical supplies. The switches’ ultra-low on-resistance and on-resistance flatness make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. The construction ensures ultra-low power dissipation, making the device suited for portable and battery-powered instruments.
The Analog Devices Inc. ADG1534 Quad SPDT 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.
