Overview
The LMH6624MF from Texas Instruments is a single ultra-low noise wideband operational amplifier. It is designed to offer high precision and wide dynamic range, making it suitable for a variety of high-performance applications. The device operates with a traditional voltage feedback topology, providing benefits such as balanced inputs, low offset voltage and current, very low offset drift, and high common mode rejection ratio (CMRR) and power supply rejection ratio (PSRR). The LMH6624MF is available in a SOT-23-5 package and operates over a temperature range of -40°C to 125°C.
