GENERAL DESCRIPTION
The ADA4930-1/ADA4930-2 are very low noise, low distortion,
high speed differential amplifiers. They are an ideal choice for
driving 1.8 V high performance ADCs with resolutions up to
14 bits from dc to 70 MHz. The adjustable output common
mode allows the ADA4930-1/ADA4930-2 to match the input of
the ADC. The internal common-mode feedback loop provides
exceptional output balance, suppression of even-order harmonic
distortion products, and dc level translation.
With the ADA4930-1/ADA4930-2, differential gain configurations
are easily realized with a simple external feedback network of
four resistors determining the closed-loop gain of the amplifier.
The ADA4930-1/ADA4930-2 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 1.2 nV/√Hz.

Figure 3. Voltage Noise Spectral Density
The low dc offset and excellent dynamic performance of the
ADA4930-1/ADA4930-2 make them well suited for a wide
variety of data acquisition and signal processing applications.
The ADA4930-1 is available in a Pb-free, 3 mm × 3 mm 16-lead
LFCSP, and the ADA4930-2 is available in a Pb-free, 4 mm × 4 mm
24-lead LFCSP. The pinout has been optimized to facilitate printed
circuit board (PCB) layout and minimize distortion. The ADA4930-1
is specified to operate over the 40°C to +105°C temperature range,
and the ADA4930-2 is specified to operate over the 40°C to +105°C
temperature range for 3.3 V or 5 V supply voltages.
