Overview
The LF411ID is a single JFET-input operational amplifier manufactured by Texas Instruments. It features a voltage-feedback architecture housed in an 8-SOIC package. Key electrical specifications include a maximum input offset voltage of 2000 µV and a typical offset drift of 10 µV/°C. The device offers a gain-bandwidth product of 2.7 MHz and a slew rate of 15 V/µs. It operates within a temperature range of 0°C to 70°C and provides a typical output current of 25 mA.
Feature Summary
- JFET input stage providing very low input bias and offset currents
- Low offset voltage and low drift characteristics for precision applications
- High output drive capability with 25 mA typical output current
Applications
- Precision instrumentation circuits
- Buffer amplifiers
- Active filters
Procurement Notes
Verify the specific suffix 'ID' confirms the industrial temperature range (0°C to 70°C) and SOIC-8 package variant. Ensure compatibility with required supply voltages and signal integrity needs. Cross-reference the manufacturer's latest datasheet revision for any pinout or electrical parameter updates before finalizing procurement orders.
Selection Notes
Select this component when low input bias current and high input impedance are critical, such as in high-impedance sensor interfaces. The JFET input technology minimizes loading effects on source circuits. Consider the 2.7 MHz bandwidth and 15 V/µs slew rate for moderate-speed signal processing tasks requiring low noise and drift performance.
Part Context
The LF411 series belongs to Texas Instruments' family of JFET-input operational amplifiers. These devices are designed to offer improved performance over standard bipolar op-amps regarding input bias current. The LF411ID specifically denotes the single-channel version in an industrial temperature grade SOIC package, distinct from dual-channel variants like the LF412.
Replacement Considerations
Compatible substitutes include the LF411CN for commercial temperature range applications or other JFET-input op-amps with similar pinouts and electrical characteristics. Verify that alternative components meet the specific offset voltage and bandwidth requirements of the design.
