LIA100

Special Purpose Amplifiers Overview

The LIA100 is a linear isolation amplifier integrating a linear optocoupler with two operational amplifiers in a single package. It provides high-performance signal transfer across an isolation barrier, featuring a bandwidth of at least 40 kHz and low non-linearity of 0.01%. The device supports wide power supply ranges from ±5V to ±18V and offers up to 5300 VAC peak input/output isolation. Available in 16-pin DIP or SOIC packages, it includes servo feedback for precision gain control.

Special Purpose Amplifiers Feature Summary

• Integrates a linear optocoupler with dual op-amps for precise isolated signal transmission
• Features servo feedback mechanism ensuring ultra-low non-linearity
• Provides high-voltage electrical isolation between input and output stages
• Supports wide operating temperature range and flexible power supply configurations

Special Purpose Amplifiers Applications

• Isolated 4-20mA converter circuits
• Medical sensor signal isolation
• Switching power supply feedback loops
• Isolated temperature and pressure sensing systems
• Data acquisition equipment requiring galvanic separation

Special Purpose Amplifiers Procurement Notes

Verify the specific package variant required, as the LIA100 designation covers multiple physical forms including standard DIP and flatpack options. Confirm bin sorting requirements if precise transfer gain (K3) matching is necessary for the application design. Check current availability status as legacy components may have limited stock or end-of-life implications.

Special Purpose Amplifiers Selection Notes

Select the LIA100 when high-precision analog isolation is required without digital conversion latency. Ensure the system can accommodate the dual supply voltage requirement within the specified ±5V to ±18V range. Consider the thermal dissipation capabilities if operating near maximum ratings, and verify that the 40kHz bandwidth meets the signal frequency requirements of the target application.

Special Purpose Amplifiers Part Context

Manufactured by IXYS Integrated Circuits Division, formerly Clare Inc., this component belongs to the family of linear isolation amplifiers designed for industrial and medical applications. It bridges the gap between discrete optocouplers and digital isolators by offering continuous analog signal transfer with high linearity and speed.
