The ADG512 are monolithic CMOS ICs containing four independently selectable analog switches. These switches feature low, well-controlled on resistance and wide analog signal range, making them ideal for precision analog signal switching.

These switch arrays are fabricated using Analog Devices’ advanced linear compatible CMOS (LC²MOS) process which offers the additional benefits of low leakage currents, ultralow power dissipation and low capacitance for fast switching speeds with minimum charge injection. These features make the ADG512 the optimum choice for a wide variety of signal switching tasks in precision analog signal processing and data acquisition systems.

The ability to operate from single +3 V, +5 V or ±5 V bipolar supplies make the ADG512 perfect for use in battery-operated instruments, 4–20 mA loop systems and with the new generation of DACs and ADCs from Analog Devices. The use of 5 V supplies and reduced operating currents give much lower power dissipation than devices operating from ±15 V supplies.

The ADG512 contain four independent SPST switches. The ADG512 differ only in that the digital control logic is inverted. The ADG511 switch is turned on with a logic low on the appropriate control input, while a logic high is required for the ADG512.
