ADG1534 1.8V Logic-Compatible Quad SPDT Switch

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 V_DD = +5V ±10% and V_SS = -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.
