Overview
The ISO120BG is a precision, low-cost isolation amplifier manufactured by Texas Instruments. It provides galvanic isolation with an insulation voltage of 3500 Vrms and supports a 3dB bandwidth of 60 kHz. The device features a common-mode rejection ratio (CMRR) of 115 dB and an input offset voltage (Vos) of 100 mV. Operating on a single supply voltage ranging from 4.5 V to 18 V, it draws a typical operating current of 6.5 mA. The component is housed in a 40-CDIP package and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides high-performance galvanic isolation for signal conditioning applications
- Features a wide common-mode rejection ratio for accurate measurement
- Supports operation over an extended industrial temperature range
Applications
- Industrial process control systems requiring isolated sensor interfaces
- Medical equipment needing patient isolation protection
- Data acquisition systems with high noise environments
Procurement Notes
Verify the specific suffix 'BG' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing board layouts designed for the CDIP-40 form factor. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when a cost-effective solution with high isolation voltage is required. The 60 kHz bandwidth suits moderate-speed applications. Consider the 40-pin DIP package constraints for PCB space. Verify that the 100 mV input offset meets system accuracy requirements without external calibration.
Part Context
The ISO120BG belongs to the ISO120 family of precision isolation amplifiers from Texas Instruments. This series is designed to replace traditional transformer-based isolation methods in analog signal chains. It integrates the isolation barrier and amplifier circuitry into a single monolithic device, simplifying design complexity compared to discrete solutions.
Replacement Considerations
The ISO120BG is functionally compatible with the ISO120. Verify if the ISO120BG-A variant is available for tighter tolerance requirements. No direct modern replacements are explicitly listed in the provided documentation.
