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.

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.

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 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.

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.
