GENERAL DESCRIPTION

The ADA4938-1 is a low noise, ultra-low distortion, high speed

differential amplifier. It is an ideal choice for driving high

performance ADCs with resolutions up to 16 bits from dc to 70

MHz. The output common mode voltage is adjustable over a

wide range, allowing the ADA4938-1 to match the input of the

ADC. The internal common mode feedback loop also provides

exceptional output balance as well as suppression of even-order

harmonic distortion products.

The ADA4938-1 is fabricated using ADI’s proprietary third

generation high-voltage XFCB process, enabling it to achieve

very low levels of distortion with input voltage noise of only 2.2

nV/√Hz. The low dc offset and excellent dynamic performance

of the ADA4938-1 make it well suited for a wide variety of data

acquisition and signal processing and applications.

The ADA4938-1 is available in a Pb-free, 3 mm x 3mm lead

frame chip scale package (LFCSP). It is specified to operate

over the extended industrial temperature range of −40°C to

+85°C.

Full differential and single-ended to differential gain

configurations are easily realized with the ADA4938-1. A

simple external feedback network of four resistors determines

the amplifier’s closed-loop gain.
