The ADA4937-1 / ADA4937-2 are low noise, ultralow distortion, high speed differential amplifiers. They are 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/ADA4937-2 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.
With the ADA4937-1 / ADA4937-2, differential gain configurations are easily realized with a simple external feedback network of four resistors that determine the closed-loop gain of the amplifier.
The ADA4937-1 / ADA4937-2 are fabricated using Analog Devices, Inc., proprietary silicon-germanium (SiGe), complementary bipolar process, enabling them 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/ADA4937-2 make them well-suited for a wide variety of data acquisition and signal processing applications.
The ADA4937-1 / ADA4937-2 are available in a Pb-free, 3 mm × 3 mm, 16-lead LFCSP (ADA4937-1, single) or a Pb-free, 4 mm × 4 mm, 24-lead LFCSP (ADA4937-2, dual). The pinout has been optimized to facilitate PCB layout and minimize distortion. The ADA4937-1 / ADA4937-2 are specified to operate over the automotive (−40°C to +105°C) temperature range and between 3.3 V and 5 V supplies.
