What are the key features of LMF380CIN/NOPB?
- 5th-order elliptic low-pass filter with sharp roll-off and high stopband attenuation
- Clock-tunable cutoff frequency allows dynamic filter adjustment without component changes
- Dual-in-line (DIP) through-hole package simplifies prototyping and breadboard development
- Single or dual supply operation for flexible analog signal chain integration
- Lead-free (NOPB) RoHS-compliant construction for global design compliance
What is LMF380CIN/NOPB used for?
Well suited for anti-aliasing and data reconstruction filters in data acquisition systems where precise, clock-programmable cutoff frequency is needed without discrete RC component changes. The LMF380CIN/NOPB is commonly used in audio processing, instrumentation front ends, and communication signal conditioning where a 5th-order elliptic response provides optimal transition band sharpness. Its DIP package makes it accessible for lab prototyping and small-volume production runs.

Frequently Asked Questions
How is the cutoff frequency of the LMF380CIN/NOPB set, and what range is achievable?
The LMF380CIN/NOPB uses a switched-capacitor architecture where the cutoff frequency is set by an external clock signal, typically at a 100:1 clock-to-cutoff ratio. This allows the filter corner to be tuned across a wide range from tens of Hz up to several hundred kHz by simply changing the clock frequency.
What filter order and response type does the LMF380CIN/NOPB implement?
The device implements a 5th-order elliptic (Cauer) low-pass filter response, which delivers steeper roll-off per decade compared to Butterworth or Chebyshev topologies, typically achieving more than 50 dB stopband attenuation within 1.5 times the cutoff frequency.
For a data acquisition front end running at 5 V, is the LMF380CIN/NOPB compatible?
Yes. The LMF380CIN/NOPB supports single-supply and dual-supply configurations, making it compatible with standard 5 V analog rails used in ADC front-end anti-aliasing filter stages for 12-bit to 16-bit data acquisition systems.
What package does the LMF380CIN/NOPB use and how does that influence procurement for legacy designs?
The part is supplied in a through-hole DIP package, which is preferred in legacy industrial and instrumentation designs that use socket-based assembly. The NOPB suffix confirms lead-free solder plating, meeting RoHS requirements without design changes to existing PCB layouts.
