Overview
The ADA4941-1YRZ-RL is a low power, low noise differential driver designed for analog-to-digital converters (ADCs) up to 18 bits. Manufactured by Analog Devices Inc., this component is ideal for systems sensitive to power consumption, such as battery-operated devices and single-supply data acquisition systems. The ADA4941-1 operates in a single-ended-to-differential configuration, requiring no external components for a gain of 2, and can achieve higher gains with a resistive feedback network. It is built on Analog Devices' proprietary second-generation eXtra fast complementary bipolar (XFCB) process, enabling high performance with low supply currents.
