Overview
The LM394CH/NOPB is a matched dual NPN transistor array manufactured by Texas Instruments. It features two closely matched transistors within a single package to ensure consistent performance characteristics between the pair. The device is designed for applications requiring precise matching, such as differential amplifiers and current mirrors. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin DIP (PDIP-8) package. The component complies with RoHS standards and is part of the LM394 series.
Feature Summary
- Integrated matched dual NPN transistor configuration for high precision
- Suitable for differential amplifier circuits requiring low offset
- Standard through-hole packaging for easy prototyping and assembly
Applications
- Precision differential amplifiers
- Current mirror circuits
- Temperature compensation networks
Procurement Notes
Verify the specific suffix CH against the official Texas Instruments datasheet to confirm the package type and temperature grade. Ensure that the NOPB designation aligns with current environmental compliance requirements. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status before procurement.
Selection Notes
Select this component when circuit design requires tightly matched transistor pairs for analog signal processing. Consider the PDIP-8 package constraints for board layout. Evaluate thermal management needs within the specified operating temperature range. Compare performance metrics against other matched transistor arrays if higher precision or different packaging is required.
Part Context
The LM394 series represents a family of matched dual NPN transistors widely used in analog integrated circuit designs. The LM394CH/NOPB variant specifically denotes the commercial temperature grade and lead-free construction. This component serves as a discrete alternative to monolithic matched pairs, offering flexibility in custom analog circuit design while maintaining manufacturing consistency.
