ASNT7113A-KHC

Overview

The ASNT7113A-KHC is a high-speed, temperature-stable, and broadband track-and-hold amplifier (THA) fabricated in SiGe technology. It features a sampling speed range from 50MSps to 4GSps and supports input data frequencies up to 20GHz. The device provides more than 8-bit accuracy across its full frequency range with a nominal 0dB differential gain. Total power consumption is 1.75W. It utilizes a custom 24-pin CQFP package with an on-chip center heat slug for thermal management.

Feature Summary

• Adjustable track period length controlled by external voltage to maximize valid output step duration
• Internal equalizer compensates for high-frequency gain drop via external control voltage
• Fully differential input and output buffers with integrated 50Ohm termination
• Dual power supply configuration supporting both negative and positive schemes

Applications

• High-speed analog-to-digital converter front-ends
• Broadband signal sampling systems
• Test and measurement instrumentation requiring precise waveform capture

Procurement Notes

Verify the specific ordering suffix matches the required package type and pinout configuration. Confirm that the procurement channel sources genuine Advanced Science And Novel Technology Company, Inc. components. Ensure compatibility with the recommended operating conditions for power supply voltages and junction temperatures during integration.

Selection Notes

Select this component when applications require sampling speeds up to 4GSps with input bandwidths reaching 20GHz. Consider the adjustable gain and equalizer controls if system-level frequency response optimization is necessary. Evaluate the dual power supply flexibility to match existing board design constraints regarding ground or power reference configurations.
