LM2937IMP-12/NOPB – TEXAS INSTRUMENTS

The LM2937IMP-12/NOPB is a single, precision, low-power, voltage-mode operational amplifier (op-amp) from Texas Instruments, packaged in an 8-lead SOIC (small outline integrated circuit) with a lead-free, halogen-free, and RoHS-compliant NOPB (no-lead, outer-lead-bond) package. It operates from a single supply voltage ranging from 2.7V to 12V, offering a wide input common-mode voltage range extending almost to the rails. This part boasts a typical input offset voltage of only 1mV and a low input bias current of 25nA, making it suitable for high-precision applications where low drift is crucial. The LM2937IMP-12/NOPB features a high gain-bandwidth product of 1MHz, enabling its use in moderately high-frequency applications. Its low power consumption, typically less than 1mW, makes it ideal for battery-powered devices. Common applications include instrumentation amplifiers, precision voltage references, and low-noise signal conditioning circuits where high accuracy and low power are paramount. The device’s high input impedance minimizes loading effects on the source signal, ensuring accurate signal amplification. The “IMP” suffix denotes its improved performance compared to earlier versions, particularly in terms of input offset voltage and temperature stability. Note that the 12V rating refers to the maximum supply voltage, not a recommended operating voltage.
