Overview
The ADG2108BCPZ-HS-RL7 is an I2C-compatible CMOS analog crosspoint switch featuring an 8 × 10 unbuffered array with 80 bidirectional channels. It supports standard, fast, and high-speed (3.4 MHz) I2C interfaces. The device operates from dual ±5 V or single +12 V supplies, offering a maximum on-resistance of 35 Ω and low quiescent current under 20 µA. It provides simultaneous switch updates via the LDSW command, readback capabilities, and a power-on reset function ensuring all switches are off at startup.
Feature Summary
- Supports high-speed I2C interface up to 3.4 MHz
- Enables simultaneous update of multiple switches using LDSW command
- Features double-buffered input logic for synchronous signal transmission
- Includes power-on reset to ensure switches are off at startup
Applications
- AV switching in TV systems
- Automotive infotainment
- CCTV applications
- Test equipment and instrumentation
Procurement Notes
Verify the -HS suffix indicates high-speed I2C support. Confirm package type matches LFCSP_WQ. Check RoHS compliance status. Ensure supply voltage requirements align with design specifications.
Selection Notes
Select this model for applications requiring high-speed I2C control. Verify operating temperature range meets system needs. Consider power supply configuration for optimal performance.
Part Context
Part of the ADG2108 family of analog crosspoint switches. Offers flexible routing with 80 channels in a compact 32-lead package. Designed for professional audio/video and industrial control systems.
Replacement Considerations
Check for availability of ADG2108BCPZ without HS suffix if high-speed interface is not required. Verify pin compatibility with existing designs.
FAQ
What is the maximum I2C clock frequency supported by this part?
The ADG2108BCPZ-HS-RL7 supports high-speed I2C operation up to 3.4 MHz.
How does the LDSW command function?
The LDSW command allows simultaneous updating of multiple switches, enabling synchronous signal transmission in latched mode.
What happens to the switches at power-up?
All switches are automatically reset to the off condition at power-up due to the internal power-on reset block.
