Overview
The LM218IDRQ1 is a dual-channel, fast general-purpose operational amplifier designed for automotive applications. It features a high slew rate of 70 V/µs and a gain-bandwidth product of 15 MHz. The device operates on a supply voltage range of ±5 V to ±20 V (single supply 10 V to 40 V). Input offset voltage is typically 2 mV, with input bias current of 30 nA. It supports an output short-circuit to ground and functions within a temperature range of -40°C to +125°C. Packaged in an 8-SOIC surface-mount format.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for grade 1 components
- High-speed performance characterized by rapid slew rates and wide bandwidth
- Robust output stage capable of handling short-circuit conditions to ground
Applications
- Automotive sensor signal conditioning circuits
- Active filter implementations in vehicle electronics
- General-purpose amplification in harsh environment systems
Procurement Notes
Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the operating environment remains within the specified -40°C to +125°C junction temperature limits. Confirm that the 8-SOIC package dimensions match the target PCB footprint requirements before finalizing integration into the design.
Selection Notes
Select this component when dual-channel operation is required alongside high-speed signal processing capabilities in automotive contexts. Compare against single-channel alternatives if pin count reduction is critical. Evaluate power consumption constraints relative to the 5 mA typical supply current per channel to ensure system efficiency targets are met without compromising speed.
Part Context
This part belongs to the LMx18 family of fast general-purpose operational amplifiers from Texas Instruments. It serves as the dual-channel variant within this lineage, offering matched performance characteristics across both channels. The family is known for providing high slew rates and wide bandwidths suitable for demanding analog signal processing tasks in industrial and automotive sectors.
Replacement Considerations
Direct substitutes include the LM218IDR and LM218N. Verify compatibility regarding automotive qualification levels and package variations when considering these alternatives.
