The ADA4941-1YRZ is a Single-supply Differential ADC Driver for ADCs up to 18-bit in systems that are sensitive to power. The low power, low noise ADC driver 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 to 3.9V on a single 5V 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. It is ideal for driving the 16-bit and 18-bit PulSAR? ADCs such as the AD7687, AD7690 and AD7691.
