The Texas Instruments LMV321IDBVR is a compact, low-power single operational amplifier designed for low-voltage analog signal-conditioning applications.
The device operates from a 2.7V to 5.5V supply voltage range, making it suitable for 3V, 3.3V and 5V electronic systems. Its low typical supply current of approximately 130uA per channel helps reduce overall system power consumption, particularly in portable and battery-powered equipment.
LMV321 provides a typical gain-bandwidth product of 1MHz and a typical slew rate of 1V/us, offering suitable dynamic performance for general-purpose amplification, buffering, filtering and sensor signal-conditioning circuits.
The amplifier features rail-to-rail output swing, allowing the output voltage to operate close to both supply rails and maximizing the available signal range in low-voltage systems. Its input common-mode range also extends slightly below the negative supply rail, providing additional design flexibility.
The LMV321IDBVR has a maximum input offset voltage of 7mV at 25°C, typical common-mode rejection ratio of approximately 65dB, and typical output-current capability of approximately 60mA.
The device operates over a wide temperature range of -40°C to +125°C, making it suitable for industrial and general embedded electronic applications.
The specific LMV321IDBVR ordering code is supplied in a compact 5-pin SOT-23 (DBV) package with tape-and-reel packaging for automated SMT production.
