AD8112JSTZ

Overview

The AD8112JSTZ is a fully buffered, nonblocking crosspoint switch matrix featuring 16 inputs and 8 outputs with a fixed gain of +2. It operates on dual supplies of ±5 V or ±12 V, consuming 34 mA to 54 mA depending on the supply voltage and output enable state. The device provides a -3 dB bandwidth of 60 MHz and supports switching times under 60 ns. Control is managed via TTL-compatible serial or parallel interfaces, allowing individual output updates or global array programming.

Feature Summary

• Supports both serial daisy-chaining and parallel programming modes for flexible system integration
• Includes dedicated output disable functionality to minimize loading when connecting multiple devices
• Features ground and power pins surrounding all analog inputs and outputs for enhanced shielding

Applications

• CCTV surveillance and digital video recording systems
• Analog and digital audio routing matrices
• Video routers supporting NTSC, PAL, S-Video, and SECAM standards
• Multimedia signal distribution systems

Procurement Notes

Verify the specific JSTZ suffix against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure that the procurement documentation explicitly references the Analog Devices datasheet for the AD8112 to validate pinout compatibility and electrical characteristics before finalizing orders.

Selection Notes

Select this component for applications requiring a 16x8 matrix topology with high-speed switching capabilities. Consider the ±12 V supply option for audio routing where higher output swing is necessary, or the ±5 V configuration for standard video applications. Evaluate thermal dissipation requirements based on the ambient temperature and load conditions to ensure operation within the specified junction temperature limits.

Part Context

This component belongs to the AD8112 series of audio/video crosspoint switches. It serves as a lower-channel-count alternative to the 16x16 AD8113, offering pin compatibility for design flexibility. The device is designed for commercial temperature ranges and utilizes a 100-lead LQFP package to accommodate the extensive I/O requirements of the switch matrix architecture.

Replacement Considerations

The AD8113 is a pin-compatible 16x16 version available from the same manufacturer. Verify interface logic levels and supply voltage requirements when substituting with other crosspoint switches, as control protocols may differ between manufacturers.
