The ADA4941-1 is a low power, low noise differential driver amplifier 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.

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 ADI’s proprietary second-generation XFCB process, which enables the amplifier to achieve 18-bit performance on low supply currents.
