AD8105ABPZ

Overview

The AD8105ABPZ is a high-speed, non-blocking analog crosspoint switch matrix featuring a 32 × 16 channel configuration. It provides a differential voltage gain of +2 and supports both single-ended and fully differential operation modes. The device offers a −3 dB bandwidth of 600 MHz with a slew rate of 1800 V/µs and a settling time of 2.5 ns to 1%. It operates on flexible power supplies, including a single +5 V or dual ±2.5 V sources, consuming approximately 340 mA of idle current. The component utilizes a double-buffered serial digital control interface or parallel programming for individual output updates. It is housed in a 304-ball BGA package (31 mm × 31 mm) and functions within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• High channel count 32 × 16 non-blocking switch array architecture
• Differential gain of +2 optimized for back-terminated load applications
• Flexible power supply options supporting single +5 V or dual ±2.5 V configurations
• Independent output buffers capable of high impedance state for bus paralleling

Applications

• RGB and component video routing
• KVM systems
• Compressed video processing (MPEG, wavelet)
• Data communications signal switching

Procurement Notes

Verify the specific ABPZ suffix against the manufacturer's ordering guide to confirm the exact package variant and temperature grade. Ensure the procurement source provides valid documentation matching the AD8104/AD8105 datasheet revision A specifications. Confirm that the delivered components are free from physical damage consistent with the 304-ball BGA form factor before integration.

Selection Notes

Select the AD8105ABPZ when a differential gain of +2 is required for driving back-terminated loads, distinguishing it from the AD8104 which has a gain of +1. Consider the 304-ball BGA package dimensions and thermal resistance characteristics during PCB layout. Verify compatibility with existing serial or parallel control logic interfaces to ensure seamless integration into the system architecture.

Part Context

The AD8105ABPZ belongs to the Analog Devices AD8104/AD8105 family of buffered analog crosspoint switches. This series is designed for high-resolution computer graphics and composite video switching applications requiring low distortion and high isolation. The AD8105 variant specifically addresses scenarios necessitating a gain of +2, while maintaining pin compatibility with the larger 32 × 32 AD8117/AD8118 arrays.

Replacement Considerations

The AD8104 serves as a functional alternative if a differential gain of +1 is acceptable. For expanded capacity requirements, the AD8117 or AD8118 provide compatible 32 × 32 architectures.
