Texas Instruments LMC6484 CMOS Quad Rail to Rail Input and Output Operational Amplifier LMC6484IM

The LMC6484 is a CMOS quad rail-to-rail input and output operational amplifier from Texas Instruments, designed for applications requiring a wide input signal range and high accuracy. It features a rail-to-rail input common-mode voltage range and output swing that can reach within 20mV of the supply rails when driving a 100kOc load. The device is specified for operation at supply voltages of 3V, 5V, and 15V, making it versatile for various low-voltage applications. With a common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 82dB, the LMC6484 ensures excellent performance in noisy environments. It has an ultra-low input current of 20fA, which is beneficial for battery-operated systems. The amplifier is suitable for driving loads down to 600Oc and is an improved replacement for older models like the TLC272 and TLC277. The LMC6484 is available in both SOIC and PDIP packages, making it adaptable for different PCB layouts. Its applications include data acquisition systems, currency counters, oscilloscopes, and various monitoring devices, making it a solid choice for engineers looking for reliable operational amplifiers in their designs.
