ADG212AKP

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG212AKP is a monolithic CMOS device comprising four independently selectable single-pole single-throw (SPST) switches. Fabricated on an enhanced LC2MOS process, it supports a maximum supply rating of 44 V and handles analog signals up to ±15 V. The device features a maximum on-resistance of 115 Ω and typical leakage currents of 0.5 nA. It operates from a single +15 V supply or dual supplies ranging from ±5 V to ±15 V. Switching times include a maximum turn-on time of 600 ns and turn-off time of 450 ns at 25°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the package type matches the specific suffix requirements, as the ADG212AKP denotes a 16-lead PDIP package. Confirm RoHS compliance status if required by the manufacturing process. Ensure the logic control inputs align with the inverted logic configuration specific to the ADG212A series compared to the ADG211A. Check for availability in the extended plastic temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG212AKP when inverted digital control logic is required relative to the standard ADG211A. Choose this component for applications demanding high breakdown voltage and ±15 V analog signal ranges. Consider the 115 Ω maximum on-resistance for signal integrity constraints. Verify that the 30 mA continuous current rating meets the load requirements of the switched circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG212AKP belongs to the ADG211A/ADG212A family of LC2MOS Quad SPST switches manufactured by Analog Devices. These devices are designed as drop-in replacements for older technologies while offering improved performance metrics. The family utilizes a high-voltage silicon-gate process to prevent latch-up and ensure reliability across wide supply voltage ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 series serves as a functional upgrade with lower on-resistance and faster switching speeds. The DG211 and DG212 devices are pin-compatible predecessors but lack the enhanced LC2MOS signal handling capabilities. Verify logic polarity differences when substituting between ADG211A and ADG212A variants within the same application design.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG212A differ from the ADG211A?

The ADG212A and ADG211A are identical in electrical specifications and pinout but differ in their digital control logic. The ADG212A uses inverted logic where a logic 1 turns the switch off, whereas the ADG211A uses non-inverted logic.

Can the ADG212AKP operate with a single supply?

Yes, the device can operate from a single +15 V supply for applications where the analog signal is unipolar (0 V to 15 V). It also supports dual supplies ranging from ±5 V to ±15 V.

What is the purpose of the break-before-make feature?

Break-before-make switching ensures that one switch opens before another closes when driven simultaneously. This prevents short circuits in multiplexer applications where multiple outputs might be tied together, keeping leakage errors to a minimum.
