ADG512BRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG512BRZ is a monolithic CMOS integrated circuit containing four independently selectable single-pole single-throw (SPST) analog switches. Fabricated using the LC2MOS process, it operates from +3 V, +5 V, or ±5 V supplies with an analog signal range extending from VSS to VDD. The device features low on-resistance of 50 Ω maximum at ±4.5 V and ultralow power dissipation under 0.5 W. It exhibits low leakage currents below 100 pA, fast switching times with a maximum turn-on time of 375 ns, and low charge injection of 11 pC typical. The digital control logic requires a high input to activate the switches.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component matches the required industrial operating range and pin configuration for the target application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low power consumption and precision switching are required within a 5 V supply environment. The ADG512 differs from the ADG511 by having non-inverted digital control logic, requiring a logic high to turn the switch on. Verify that the on-resistance and leakage specifications meet the system requirements for the intended signal range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG512BRZ belongs to the ADG511/ADG512/ADG513 family of precision 5 V/3 V quad SPST switches. These devices share the same LC2MOS fabrication process but differ in their digital control logic configurations. The ADG512 specifically utilizes non-inverted logic compared to the ADG511.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG511BRZ is a functional substitute within the same family but requires inverted logic control. The ADG513BRZ offers mixed logic states across its four channels. Verify logic compatibility before substituting these variants.
