Frequently Asked Questions
What is the input bias current of the LMC6081IN/NOPB?
The LMC6081IN/NOPB features an ultra-low input bias current of 10fA (femtoamperes) typical, making it one of the lowest in its class. This extremely high input impedance is essential for applications like photodiode amplifiers, pH probes, and other high-impedance sensor interfaces where even picoampere-level leakage currents can introduce significant measurement errors.
What supply voltage does the LMC6081IN/NOPB support?
The LMC6081IN/NOPB operates from a single supply of 4.5V to 15.5V or a dual supply of ±2.25V to ±7.75V. It offers rail-to-rail input common-mode range across the full supply voltage, enabling flexible design in both 5V and 3.3V single-supply systems commonly found in portable and battery-operated equipment.
What package does the LMC6081IN/NOPB come in?
The LMC6081IN/NOPB is housed in an 8-pin PDIP (DIP-8) through-hole package, suitable for prototyping and applications where through-hole assembly is preferred. Texas Instruments also offers the LMC6081 in surface-mount packages such as SOIC-8 for production designs. The /NOPB suffix indicates the device is lead-free and RoHS compliant.
What are typical applications for the LMC6081IN/NOPB?
The LMC6081IN/NOPB is widely used in precision instrumentation, photodiode transimpedance amplifiers, medical measurement equipment, pH and ion-selective electrode interfaces, capacitive sensor readouts, active filters, and battery-powered data acquisition systems. Its combination of ultra-low input bias current, rail-to-rail input, and low offset voltage (350μV max) makes it highly suitable for any application requiring precise, low-noise signal conditioning from high-impedance sources.
How does the LMC6081IN/NOPB compare to the LM741 or TL071?
Compared to the classic LM741 (input bias current ~80nA) or TL071 (30pA), the LMC6081IN/NOPB offers dramatically lower input bias current at just 10fA — approximately 3 million times lower than the LM741. This CMOS-input precision amplifier also provides rail-to-rail input range and lower offset voltage (350μV max vs. 6mV for LM741), making it a superior choice for modern precision and high-impedance measurement designs.
