GENERAL DESCRIPTION  
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.  
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 ADIs proprietary second-  
generation 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.  
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.
