Frequently Asked Questions
What is the supply voltage range of the LMC6484IM/NOPB?
The LMC6484IM/NOPB operates from a single supply voltage of 3V to 15V, or a dual supply of ±1.5V to ±7.5V. This wide range makes it suitable for both 3.3V and 5V microcontroller-based systems as well as higher-voltage industrial applications.
What does the rail-to-rail input/output capability mean for circuit design?
Rail-to-rail input means the common-mode input voltage can span the full supply range from V– to V+, eliminating headroom concerns. Rail-to-rail output means the output can swing to within millivolts of either supply rail, maximizing dynamic range especially in low-supply-voltage systems. Together, these features simplify single-supply circuit design and allow the amplifier to handle signals that approach the supply limits.
What is the typical input bias current of the LMC6484IM/NOPB?
The CMOS input stage of the LMC6484IM/NOPB provides an extremely low typical input bias current of just 40 fA (femtoamperes). This near-zero bias current makes it ideal for high-impedance sensor interfaces, charge amplifiers, and circuits with large feedback resistors where conventional BJT op-amps would introduce significant error.
What are common applications for the LMC6484IM/NOPB?
Common applications include battery-powered portable instrumentation, sensor signal conditioning (thermocouple, pressure, photodiode), active filters, sample-and-hold circuits, precision comparators, data acquisition front ends, and any low-power analog circuit requiring four op-amps in a compact SOIC-14 package.
Can the LMC6484IM/NOPB replace other quad op-amps like the LM324?
The LMC6484IM/NOPB is a functional upgrade to older quad op-amps such as the LM324 in many designs, offering true rail-to-rail output (vs. the LM324's limited low-side swing), drastically lower input bias current, and lower supply current. However, designers should verify supply voltage compatibility and bandwidth requirements, as the LMC6484 has a 1.5 MHz GBW compared to the LM324's 1 MHz, and confirm the SOIC-14 footprint matches the target PCB layout.
