Overview
The LMV324IDR is a low-voltage, rail-to-rail output operational amplifier produced by Texas Instruments. This device is part of the LMV series, designed for operation at voltages as low as 2.7 V and up to 5.5 V. The LMV324IDR features four independent operational amplifiers in a single 14-pin SOIC package, making it a versatile component for various applications requiring multiple amplification stages.
It is particularly suited for low-power, low-voltage systems due to its low supply current and high performance characteristics such as a gain bandwidth product of 1 MHz and a slew rate of 1 V/μs. The device also offers rail-to-rail output swing and ESD protection, enhancing its reliability in diverse operational environments.
