Frequently Asked Questions
What is the input bias current of the LF412CDR?
The LF412CDR features an exceptionally low input bias current of 0.0002µA (0.2nA) at 25°C, with a maximum of 0.008µA. This ultra-low bias current makes it ideal for high-impedance sensor interfaces, charge amplifiers, and precision instrumentation where leakage current must be minimized.
What are the typical applications for the LF412CDR op-amp?
The LF412CDR is commonly used in precision instrumentation amplifiers, active filter designs, sample-and-hold circuits, medical equipment, audio signal processing, and industrial sensor interfaces. Its dual-channel design, 3MHz bandwidth, and 100dB CMRR make it well-suited for differential signal amplification and low-noise analog front-end circuits.
What package does the LF412CDR come in and what is the pin count?
The LF412CDR comes in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated as the 'D' suffix in TI's naming convention. The SOIC package offers a compact SMD footprint compatible with standard PCB assembly processes, with a 1.27mm pin pitch widely supported by reflow soldering.
Is the LF412CDR RoHS compliant and still in production?
Yes, the LF412CDR is Pb-free (lead-free) and RoHS compliant, as indicated by the 'Pbfree Code: Yes' specification. Originally introduced in March 1989, this device remains in active production with a long estimated end-of-life timeline (YTEOL: 15 years), ensuring long-term supply availability for your designs.
