OPA2320AQDGKRQ1 General Description

The OPA2320AQDGKRQ1 is a high precision, low-power operational amplifier designed for automotive applications. It has a wide operating voltage range of 2.5V to 5.5V and a low quiescent current of only 600μA per channel. This makes it ideal for battery-powered systems where power consumption is critical.This operational amplifier features rail-to-rail input and output voltage ranges, allowing it to work effectively with low voltage signals. It has a high common-mode rejection ratio (CMRR) and a high open-loop gain, ensuring accuracy and stability in a variety of applications.The OPA2320AQDGKRQ1 is designed to operate in harsh automotive environments, with a temperature range of -40°C to 125°C and enhanced electrostatic discharge (ESD) protection. It is available in a small MSOP-8 package, making it suitable for space-constrained applications.
