JM38510/11905BGA

Overview

The JM38510/11905BGA is a dual-channel J-FET input operational amplifier manufactured by National Semiconductor. It features two circuits housed in a 10-lead Ceramic Flat Pack (CFP) package. The device is characterized as a high-speed, low-noise amplifier with very low input offset voltage and guaranteed input offset voltage drift. Designed for precision analog applications, it offers low input bias current and low noise performance, making it suitable for instrumentation and general-purpose op-amp roles requiring high accuracy.

Feature Summary

• Dual-channel J-FET input architecture providing low input bias current
• Guaranteed low input offset voltage and low drift characteristics
• High-speed operation with low noise profile
• Hermetic ceramic flat pack packaging for reliability

Applications

• Precision instrumentation systems
• Low-noise signal conditioning circuits
• High-accuracy data acquisition front ends

Procurement Notes

Verify the manufacturer source carefully, as National Semiconductor's semiconductor assets were acquired by Texas Instruments. Confirm that the specific BGA suffix corresponds to the intended ceramic flat pack variant and check for RoHS compliance status if required for modern assembly processes. Ensure the part number matches the exact military or commercial grade specifications documented in the official datasheet.

Selection Notes

Select this component when low input bias current and minimal offset drift are critical requirements. The dual-channel configuration allows for space-efficient designs in precision analog circuits. Consider the CFP package constraints regarding board layout and thermal management compared to surface-mount alternatives.

Part Context

This part belongs to the JM38510 series of dual operational amplifiers. The 'BGA' suffix typically denotes a specific package type or temperature range within the National Semiconductor product line. These devices are often used in applications requiring stable performance over time and temperature variations.

Replacement Considerations

Check for direct equivalents from Texas Instruments following the acquisition. Verify pin compatibility and electrical parameters against other dual JFET op-amps in the LMH6629 or similar families if available.
