The ADA4941-1 is a low power, low noise differential driver for ADCs up to 18 bits in systems that are sensitive to power. The ADA4941-1 is configured in an easy-to-use, single-ended-to-differential configuration and requires no external components for a gain of 2 configuration. A resistive feedback network can be added to achieve gains greater than 2. The ADA4941-1 provides essential benefits, such as low distortion and high SNR, that are required for driving high resolution ADCs.
With a wide input voltage range (0 V to 3.9 V on a single 5 V supply), rail-to-rail output, high input impedance, and a user-adjustable gain, the ADA4941-1 is designed to drive single-supply ADCs with differential inputs found in a variety of low power applications, including battery-operated devices and single-supply data acquisition systems.
