TILM321LVIDBVR
Overview
The LM321LVIDBVR is a low-voltage, general-purpose operational amplifier designed for cost-sensitive applications requiring a balance of performance and power consumption. It features a 1 MHz gain bandwidth product and a 1.5 V/us slew rate while consuming only 90 uA of supply current. The device is unity-gain stable and includes a common-mode input range that extends to the negative rail, making it suitable for single-supply operation.
Why Choose This Part
This amplifier offers a significantly improved slew rate of 1.5 V/us compared to older industry-standard LM321 variants while maintaining a low power profile. Its low input offset voltage of 1 mV and integrated ESD protection of 2-kV HBM provide enhanced reliability and precision for general-purpose analog designs. The compact SOT-23-5 package allows for high-density PCB layouts in space-constrained applications.
Applications
Key Specifications
Getting Started
To evaluate the LM321LV, it can be prototyped using a standard SOT-23 to DIP adapter or integrated directly into a PCB following the datasheet layout guidelines for decoupling. Ensure a 0.1 uF ceramic capacitor is placed close to the V+ pin for power supply stability. The device operates across a supply range of 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems.
