AD8113JST

Analog Switches, Multiplexers, Demultiplexers Overview

The AD8113JST is a fully buffered 16x16 crosspoint switch matrix with a gain of +2. It operates on ±5 V for video or ±12 V for audio supplies, consuming 54 mA. Key electrical parameters include a –3 dB bandwidth of 60 MHz, crosstalk of –83 dB at 20 kHz, and total harmonic distortion of 0.002% at 20 kHz. The device features serial or parallel programming, output disable capabilities, and a reset pin for power-on initialization.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix JST corresponds to the 100-lead LQFP package and commercial temperature range (0°C to 70°C). Confirm supply voltage requirements match application needs, as performance varies between ±5 V and ±12 V operation. Ensure proper ESD handling during assembly due to device sensitivity. Check for any updated revision notes regarding thermal derating curves.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low distortion and high isolation in audio or video routing. Choose ±12 V supplies for audio applications to achieve higher output swing and lower distortion. Use ±5 V supplies for video applications to drive standard loads like 150 Ω. Consider power dissipation limits when operating at higher ambient temperatures or driving heavy loads.

Analog Switches, Multiplexers, Demultiplexers Part Context

The AD8113 is part of Analog Devices' family of high-performance analog crosspoint switches. It is designed for demanding audio and video routing environments where signal integrity is critical. The device integrates 16 independent output buffers and decoding logic into a single 100-lead package, simplifying system design compared to discrete solutions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes are not available in the provided documentation. Verify compatibility with existing control logic levels (TTL compatible) if replacing similar crosspoint switches. Ensure thermal management strategies are adequate for the replacement package type.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the AD8113 handle input bias current?

The AD8113 uses a unique bias current compensation scheme that samples and cancels contributions from each transconductance stage, keeping residual bias current nominally zero regardless of the number of enabled inputs.

What is the maximum allowed junction temperature?

For long-term reliability, the maximum allowed junction temperature should not exceed 150°C. Exceeding 175°C for extended periods can result in device failure.

Can multiple AD8113 devices be connected together?

Yes, unused outputs can be disabled to minimize loading, allowing multiple ICs to be bused together for creating larger switch arrays via serial daisy-chaining.
