ADG1312YRZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1312YRZ-REEL7 is a monolithic CMOS device containing four independently selectable single-pole/single-throw (SPST) switches. It operates on a 33 V supply range, fully specified at +12 V single supply or ±15 V dual supply. The Y version supports an operating temperature range of -40°C to +105°C and is housed in a 16-lead SOIC package. Key electrical parameters include a maximum on resistance of 200 Ω at ±13.5 V supplies, with typical values of 130 Ω. Dynamic characteristics feature a maximum turn-on time of 125 ns and turn-off time of 50 ns at ±10 V. Power consumption is minimal, with typical supply currents of 220 μA at 5 V logic inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features 3 V logic-compatible digital inputs that eliminate the need for a separate VL logic power supply.
• Provides rail-to-rail analog signal operation, allowing input signals to extend to the positive and negative supply rails.
• Offers bidirectional conduction where each switch conducts equally well in both directions when active.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal switching
• Battery-powered systems
• Communication systems
• Audio/video signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm the Y suffix denotes the industrial temperature grade (-40°C to +105°C). Ensure the Z suffix confirms RoHS compliance status as per the manufacturer's ordering guide. Cross-reference the SOIC-16 package dimensions against your PCB footprint requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG1312 variant specifically when high-level logic control is required to activate the switches, distinguishing it from the ADG1311 which uses inverted logic. Consider the ADG1313 if break-before-make switching action is necessary for multiplexer applications. Evaluate the 200 Ω maximum on resistance against your signal integrity requirements compared to lower resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG1311/ADG1312/ADG1313 family of low capacitance, low charge injection quad SPST switches. The ADG1312 differs from the ADG1311 solely by its non-inverted digital control logic. Both devices share identical analog performance specifications and are designed for standard performance applications requiring robust signal routing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1311YRZ-REEL7 serves as a direct functional substitute if the circuit design accommodates inverted logic control (Logic 0 turns on). The ADG1313YRZ-REEL7 is suitable if break-before-make timing is required, though it features mixed logic polarity across its channels.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the digital control logic of the ADG1312 differ from the ADG1311?

The ADG1312 requires a Logic 1 input to turn the switches on, whereas the ADG1311 requires a Logic 0 input. The analog performance remains identical between the two.

What is the maximum continuous current rating for the switches?

The continuous current per channel for either the Source (S) or Drain (D) terminal is rated at 25 mA.

Does this device require a separate voltage supply for the logic inputs?

No, the ADG1312 features 3 V logic-compatible inputs that do not require a separate VL supply voltage.
