ISO107

Overview

The ISO107 is a high-voltage isolation amplifier providing signal and power across an isolation barrier in a 32-pin side-braze ceramic package. It features a transformer-coupled DC/DC converter and capacitor-coupled signal channel. Key electrical specifications include a nominal gain of 1 V/V, a small-signal bandwidth of 20 kHz, and a rated continuous AC voltage of 2500 Vrms with an 8000 Vpk test breakdown voltage. The device operates within a temperature range of -25°C to +85°C.

Feature Summary

• Integrates isolated power generation and signal transmission within a single hybrid package
• Provides wide input signal range capability from -10V to +10V
• Supports multichannel synchronization via TTL clock signals for synchronized operation
• Includes internal current limiting and soft-start protection for the isolated power supply

Applications

• Multichannel isolated data acquisition systems
• Biomedical instrumentation requiring galvanic isolation
• Power supply and motor control circuits
• Ground loop elimination applications

Procurement Notes

Verify component status as NRND (Not Recommended for New Designs). Confirm availability through existing production channels or lifetime-buy periods if applicable. Ensure design compliance with UL544 test methods regarding isolation barrier integrity. Review absolute maximum ratings carefully during integration to prevent damage from overvoltage conditions.

Selection Notes

Select this component when simultaneous isolated power delivery and high-voltage signal isolation are required in a compact form factor. Consider the 32-pin ceramic package constraints and thermal management requirements for the specified operating temperature range. Evaluate the need for external synchronization logic if multiple units must operate coherently without beat frequency interference.

Part Context

Manufactured by Burr-Brown Corporation, now part of Texas Instruments. The ISO107 utilizes a proprietary square core wirebonded transformer and duty-cycle modulation technology. It represents a specialized solution for high-reliability analog isolation where traditional optocouplers or digital isolators cannot provide the necessary combined power and precision signal transfer capabilities.
