Overview
The LF256H/NOPB is a single-channel operational amplifier from Texas Instruments featuring FET input technology. It operates within a supply voltage range of 10 V to 44 V, with dual supplies between ±5 V and ±22 V. Key electrical parameters include a gain-bandwidth product of 5 MHz, a slew rate of 12 V/µs, and an input bias current of 100 pA. The device delivers an output current of 25 mA per channel and maintains a typical common-mode rejection ratio of 100 dB. It functions reliably across temperatures from -25°C to +85°C.
Feature Summary
- FET input stage providing low input bias current
- High common-mode rejection ratio for signal integrity
- Wide single or dual power supply operation
Applications
- Precision analog signal conditioning circuits
- High-impedance sensor interfaces
- Low-noise preamplifier stages
Procurement Notes
Verify the specific suffix 'H' against the manufacturer's current datasheet to confirm package type and temperature grade specifications. Ensure the 'NOPB' designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the Mouser part number 926-LF256H to validate availability and exact component revision before finalizing procurement orders.
Selection Notes
Select this component when high input impedance and moderate bandwidth are required without the need for shutdown functionality. Compare the 100 pA input bias current against bipolar alternatives if leakage currents must be minimized. Consider the TO-99-8 package constraints for through-hole mounting versus surface-mount options available in other series members.
Part Context
This device belongs to the LF256 series of precision operational amplifiers manufactured by Texas Instruments. It shares architectural similarities with the LF356 but offers distinct input characteristics suited for specific high-impedance applications. The series is designed for general-purpose analog processing where stability and wide supply voltage ranges are critical design factors.
Replacement Considerations
The LF356H/NOPB serves as a verified substitute within the same family, offering similar performance metrics with slight variations in input bias current specifications.
