The ADA4941-1 is a low power, low noise differential driver for analog-to-digital converters (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 singlesupply data acquisition systems.

The ADA4941-1 is ideal for driving the 16-bit and 18-bit PulSAR® ADCs, such as the AD7687, AD7690, and AD7691. The ADA4941-1 is manufactured on Analog Devices, Inc., proprietary, second-generation, eXtra fast complementary bipolar (XFCB) process, which enables the amplifier to achieve 18-bit performance on low supply currents.

The ADA4941-1 is available in a small 8-lead LFCSP as well as a standard 8-lead SOIC and is rated to work over the extended industrial temperature range, −40°C to +125°C.

Product Detail

The Universal Differential Amplifier Evaluation Boards can be used to evaluate single, high speed, fully differential amplifiers. The evaluation boards are bare boards that enable users to quickly prototype a variety of differential or single-ended circuits, which minimizes risk and reduces time to market. These boards are all RoHs Compliant. See references below on what board to order by lead count and package.
