Overview
The LF353M/NOPB is a dual wideband high-speed JFET input operational amplifier utilizing BI-FET II technology for internally trimmed input offset voltage. It features low power supply current of 3.6 mA while maintaining a gain-bandwidth product of 4 MHz and a slew rate of 13 V/µs. The device offers very low input bias and offset currents due to matched high-voltage JFET input devices, with an input impedance of 10^12 Ω. It operates on supply voltages ranging from 10 V to 36 V (±5 V to ±18 V) in an 8-pin SOIC package.
Feature Summary
- BI-FET II technology provides internally adjusted input offset voltage for improved precision.
- High input impedance combined with low input bias current minimizes loading effects on signal sources.
- Wide bandwidth and fast slew rate support high-frequency signal processing applications.
Applications
- High-speed integrators
- Fast digital-to-analog converters
- Sample-and-hold circuits
Procurement Notes
Verify the specific suffix 'M' corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status as indicated by the NOPB designation. Ensure the operating environment remains within the specified temperature range for optimal performance stability.
Selection Notes
Select this component for designs requiring JFET input characteristics such as high impedance and low bias current without the complexity of external trimming. It serves as a direct upgrade path for existing LM1558 or LM358 designs where higher speed and lower noise are required.
Part Context
This part belongs to the LF353 family of dual JFET-input operational amplifiers manufactured by Texas Instruments. The family is characterized by its combination of high-speed performance and low power consumption, making it suitable for general-purpose analog signal conditioning tasks that demand better noise and impedance specifications than standard bipolar op-amps.
Replacement Considerations
The LF353M/NOPB is listed as a manufacturer-recommended replacement for the discontinued LF353M. Designers should verify pin compatibility and electrical parameter tolerances against legacy components like the LM1558 before implementation.
