Ultralow Power, Low Distortion ADC Driver
With the ADA4940-1/ADA4940-2, differential gain configurations are easily realized with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier. The ADA4940-1/ADA4940-2 are fabricated using Analog Devices, Inc., complementary bipolar process, enabling them to achieve very low levels of distortion with an input voltage noise of only 3.9 nV/√Hz. The low dc offset and excellent dynamic performance of the ADA4940-1/ADA4940-2 make them well suited for a variety of data acquisition and signal processing applications.
The ADA4940-1 is available in a Pb-free, 3 mm × 3 mm, 16-lead LFCSP. The ADA4940-2 is available in a Pb-free, 4 mm × 4 mm, 24-lead LFCSP. The pinout is optimized to facilitate printed circuit board (PCB) layout and minimize distortion. The ADA4940-1/ADA4940-2 are specified to operate over the −40°C to +125°C temperature range.

The ADA4940-2ACP-EBZ evaluation board aids in the testing of the ADA4940-2 dual high speed differential amplifier. The ADA4940-2ACP-EBZ is a bare board, that is there are no components soldered to the board. This enables users to customize the circuit and quickly prototype a variety of differential amplifier circuits, which minimizes risk and reduces time to market. This evaluation board will also support any of the Analog Devices, Inc., ADA49XX series of dual high speed differential amplifiers.
