Product Overview
National Semiconductor LMC6482AIN CMOS Dual Rail-to-Rail Op Amp, 8-Pin Plastic DIP
Condition
New, unused stock. The topside carries the National Semiconductor logo followed by M68AF on the first line, with LMC64 and 82AIN reading across the two lines below it, so the full LMC6482AIN part number is legible in the photos. The body is a molded 8-pin plastic DIP with the pin 1 notch and dimple at one end, and the underside carries a molded circular mark reading AQ E02. Leads are bright, straight, and carry no solder, flux, or board residue. Shot loose in hand and against bubble wrap so you can read the marking and inspect the leads before you order. Stock on hand at the time of writing is 49 pieces, and you choose the count.

Product Overview
The LMC6482AIN is a CMOS dual operational amplifier with rail-to-rail input and output, packaged in the 8-pin through-hole plastic DIP that the N suffix designates. Two independent amplifiers share the one package, which is why this part turns up in data acquisition front ends, transducer amplifiers, hand-held analytic instruments, and medical instrumentation, along with active filters, peak detectors, sample and hold stages, pH meters, and current sources. Rail-to-rail behavior is the reason designers reach for it: the signal is not clipped short of the supply, which matters most in single-supply and battery-powered gear where every millivolt of headroom counts. The pieces photographed here are marked with the National Semiconductor logo; National's amplifier lines moved to Texas Instruments after the 2011 acquisition, so current datasheets for this device are published under the TI listing of the same part number. Supply range, offset voltage, and bandwidth figures are not confirmed here - pull the datasheet and verify against your design before you commit.
Key Features

Applications
- Instrumentation technician building a pH meter front end that has to swing close to both supply rails
- Design engineer prototyping a battery-powered hand-held analytic instrument where supply headroom is scarce
- Service tech repairing an older data acquisition or medical instrumentation board that used a dual CMOS amplifier
- Bench builder laying out active filter, peak detector, or sample and hold stages on perfboard or a socketed prototype
Frequently Asked Questions
What does the N in LMC6482AIN tell me about the package?
In National's part numbering the N suffix denotes the plastic DIP package, and that matches what the photos show: an 8-pin molded plastic body with straight through-hole leads and a pin 1 notch. If your board is laid out for a surface-mount version of this amplifier, this is not the package you want.
What are the M68AF and AQ E02 markings?
Those are factory markings on the pieces we photographed. M68AF sits above the part number on the topside and AQ E02 is molded into a circular pad on the underside. We do not decode National's internal lot and cavity coding, and we cannot promise every piece pulled from stock carries the identical set of codes.
Are these tested, and what condition am I getting?
These are new, unused parts that have never been installed - the leads are bright and unsoldered in every photo. We do not bench test individual pieces, so treat the photographs and the printed part number as what is confirmed, and verify electrical parameters against the datasheet for your design.
Can I socket these instead of soldering them?
The photos show a standard 8-pin DIP body with straight, unformed leads, which is the shape an 8-pin DIP socket expects. That is a physical observation from these pieces, not a fit guarantee for a specific socket, so match the socket to your board and check the seating before you commit a build.
I only need two of these, not a full tube. Can I buy that few?
Yes. Order the exact count your work needs, whether that is one piece to fix a channel on a repaired board or a few for a prototype run, rather than paying for a sealed tube or a bagged lot of 25 or 50 and storing the rest in a drawer for a decade. You pick the quantity at checkout and it comes off the shelf stock shown in these photos. Shipping is $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
CMOS amplifiers that swing all the way to both rails are what made single-supply, battery-powered instruments practical, and National put that trick in an 8-pin DIP you can still push straight into a breadboard. Wire it into the pH meter, the filter stage, or whatever circuit of yours needs the last few millivolts of headroom.
