Overview
The ISO122PG4 is a precision isolation amplifier manufactured by Texas Instruments, housed in an 8-pin DIP package. It features a duty cycle modulation-demodulation technique for signal transmission. The device supports a supply voltage span of 9 V to 36 V and operates within a temperature range of -25°C to 85°C. Key electrical specifications include a slew rate of 2 V/µs, a nominal bandwidth of 50 MHz, and a maximum common-mode voltage of 1500 Vrms. It draws 5 mA of supply current and provides 15 mA output current per channel.
Feature Summary
- Utilizes duty cycle modulation-demodulation technique for signal transmission
- Provides high immunity to common-mode transients with 140 dB IMR at 60 Hz
- Offers precision performance with low input offset voltage
Applications
- Industrial process control systems
- Medical equipment requiring galvanic isolation
- Data acquisition systems
Procurement Notes
Verify the specific suffix PG4 confirms the 8-pin DIP package variant. Confirm the component status as discontinued or active through official Texas Instruments channels prior to procurement. Ensure the operating temperature range meets system requirements. Check for RoHS compliance documentation if required by regulatory standards.
Selection Notes
Select this component when high-precision analog signal isolation is required in industrial environments. The 1500 Vrms isolation rating suits applications with significant ground potential differences. Consider the 50 MHz bandwidth for higher frequency signal processing needs. Verify that the 8-pin DIP package fits the target PCB layout constraints.
Part Context
This part belongs to the ISO122 family of precision isolation amplifiers from Texas Instruments. These devices are designed to provide accurate signal transfer across isolation barriers while rejecting common-mode noise. The family typically includes variants with different packaging options to suit various assembly requirements.
Replacement Considerations
Check for ISO122UE4 as a potential alternative with SOIC packaging. Verify pin compatibility and electrical specifications before substitution. Confirm availability status as the PG4 variant may be discontinued.
