GENERAL DESCRIPTION

The ADA4937-1 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

100 MHz. The adjustable level of the output common mode

allows the ADA4937-1 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.

simple external feedback network of four resistors determines

the amplifier’s closed-loop gain.

The ADA4937-1 is fabricated using ADI’s proprietary third

generation 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

ADA4937-1 make it well suited for a wide variety of data

acquisition and signal processing and applications.

Full differential and single-ended to differential gain

configurations are easily realized with the ADA4937-1. A

The ADA4937-1 is available in a Pb-free, 3 mm x 3mm lead

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

over the temperature range of −40°C to +105°C.
