GENERAL DESCRIPTION
The ADA4930-1-EP is a very low noise, low distortion, high
speed differential amplifier. It is 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 voltage setting
allows the ADA4930-1-EP to match the input of the ADC for
maximum dynamic range. The internal common-mode feedback
loop provides exceptional output balance, suppression of even-
order harmonic distortion products, and dc level translation.

Figure 2. Voltage Noise Spectral Density
With the ADA4930-1-EP, 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-EP 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 1.2 nV/√Hz.
The low dc offset and excellent dynamic performance of the
ADA4930-1-EP make it well suited for a wide variety of data
acquisition and signal processing applications.
The ADA4930-1-EP is available in a 3 mm × 3 mm 16-lead LFCSP.
The pinout has been optimized to facilitate printed circuit board
(PCB) layout and minimize distortion. The ADA4930-1-EP is
specified to operate over the −55°C to +105°C temperature range for
3.3 V or 5 V supply voltages.
Additional application and technical information can be found
in the ADA4930-1/ADA4930-2 data sheet.
