Overview
The LF412ACN is a dual JFET-input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 3 MHz and a slew rate of 15 V/µs. The device operates on a supply voltage range of 10 V to 36 V or ±5 V to ±18 V, with a maximum supply voltage of 40 V. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 50 pA, and input noise voltage density of 18 nV/√Hz. It provides a common-mode rejection ratio of 70 dB and can deliver up to 25 mA output current per channel. The component is housed in an 8-pin DIP package.
Feature Summary
- JFET input stage providing low input bias current
- High-speed performance suitable for signal processing
- Wide single or dual power supply operation
Applications
- Audio preamplifiers
- Active filters
- Integrators and differentiators
Procurement Notes
Verify the specific suffix 'ACN' against the official Texas Instruments datasheet to confirm the temperature grade and package variant. Ensure the ordering part number matches the required industrial specifications. Cross-reference the manufacturer's latest documentation to validate RoHS compliance status and pinout configuration before finalizing procurement.
Selection Notes
Select this component when low input bias current and high slew rate are required for analog signal conditioning. Compare the 1 mV input offset voltage against application tolerance requirements. Consider the 8-pin DIP package for through-hole prototyping or legacy board designs requiring dual-channel amplification within a standard supply voltage range.
Part Context
The LF412ACN belongs to the LF412 family of dual JFET-input operational amplifiers from Texas Instruments. This series is designed for applications requiring high input impedance and fast transient response. The ACN designation typically indicates a specific temperature range and packaging format within the broader LF412 product line, distinguishing it from other variants like the LF412CP or LF412CD.
Replacement Considerations
Official substitutes may include the LF412CN or LF412CDR from Texas Instruments, provided they meet the same electrical specifications and package requirements. Verify compatibility with existing circuit designs before substitution.
