GENERAL DESCRIPTION

The ADA4937-1 is a low noise, ultralow 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.

The ADA4937-1 is fabricated using Analog Devices, Inc.

proprietary silicon-germanium (SiGe), complementary bipolar

process, enabling it to achieve very low levels of distortion with

an 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 applications.

The ADA4937-1 is available in a Pb-free, 3 mm × 3 mm 16-lead

LFCSP. The pinout has been optimized to facilitate PCB layout

and minimize distortion. The part is specified to operate over

the −40°C to +105°C temperature range for 3.3 V supplies and

the −40°C to +85°C temperature range for 5 V supplies.

With the ADA4937-1, differential gain configurations are easily

realized with a simple external feedback network of four

resistors determining the closed-loop gain of the amplifier.
