Overview
The OPA244NA/3KG4 is a single-channel operational amplifier from Texas Instruments, part of the OPA244 series. This MicroPower op amp is designed for very low quiescent current (50µA/channel) while maintaining excellent bandwidth and performance. It is ideal for battery-powered and portable instrumentation due to its low power consumption and compact packaging. The OPA244NA/3KG4 is available in the SOT-23-5 surface-mount package, making it suitable for space-limited applications.
