ADG662BRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG662BRUZ is a precision quad SPST analog switch from Analog Devices, fabricated using LC2MOS technology. It operates on a single +5 V supply or dual ±5 V supplies. Key electrical parameters include a maximum on-resistance of 75 Ω (single supply) or 50 Ω (dual supply), and ultralow leakage currents with a maximum OFF leakage of ±2.5 nA. The device features fast switching times, with typical turn-on and turn-off delays of 250 ns and 45 ns respectively under single-supply conditions. It exhibits low charge injection of 12 pC and supports an analog signal range extending to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints, specifically the 16-lead TSSOP outline. Confirm that the digital control logic polarity matches the system design, as the ADG662 requires a logic high to activate switches. Check for any recent product change notices regarding manufacturing locations or material compositions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG662BRUZ when low charge injection and ultralow power consumption are critical. Choose this part over the ADG661 if the system requires active-high logic control for switch activation. Consider the ADG663 if mixed logic polarities are needed within the same package. Evaluate the on-resistance flatness requirements for audio applications, as the LC2MOS process ensures excellent linearity across the full analog input range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG662BRUZ belongs to the ADG661/ADG662/ADG663 family of precision 5 V quad SPST switches. These devices utilize Analog Devices' advanced linear compatible CMOS process to achieve low leakage and low capacitance. The family differentiates primarily by digital control logic inversion: the ADG662 uses active-high logic, whereas the ADG661 uses active-low logic. All variants share identical analog performance characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the ADG661BRUZ and ADG663BRUZ. The ADG661BRUZ offers identical analog performance but utilizes inverted digital control logic (active-low). The ADG663BRUZ provides mixed logic polarities within the same package. Direct functional replacement requires verifying that the control interface logic levels align with the selected substitute's truth table.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between ADG661 and ADG662?

The ADG661 and ADG662 have identical analog specifications and pinouts. The only difference is the digital control logic: the ADG661 switches turn on with a logic low input, while the ADG662 switches turn on with a logic high input.

Does the ADG662 support break-before-make switching?

Yes, the ADG662 features inherent break-before-make switching action. This prevents channel shorting when multiple switches are configured as a multiplexer, ensuring safe signal routing during state transitions.

What is the typical charge injection for the ADG662?

The typical charge injection for the ADG662 is 12 pC under single-supply conditions and 6 pC under dual-supply conditions. This low value minimizes transients when switching digital inputs.
