The ADL5567 is a high performance, dual differential amplifier that operates up to 4.3 GHz. This amplifier offers a low noise of 1.29 nV/vHz and excellent distortion performance. It provides a gain of 20 dB and for the single-ended input configuration, the gain is reduced to 18 dB.

Using two external series resistors for each amplifier expands the gain flexibility of the amplifier and allows for any gain selection from 0 dB to 20 dB for a differential input and 0 dB to 18 dB for a single-ended input. This device maintains low distortion down to output common-mode levels of 1.25 V, and provides an added capability for driving CMOS ADCs at ac levels up to 2 V p-p. It has a quiescent current of typically 74 mA per amplifier in high performance mode using a 5 V supply. When disabled, each amplifier consumes only 3.5 mA, and has 58 dB input to output isolation at 100 MHz.

The dual differential amplifier is optimized for wideband, low distortion, and low noise operation, giving it unprecedented performance for overall spurious-free dynamic range (SFDR). It is available in a compact 4 mm 4 mm, 24-lead LFCSP package and is ideally suited for use in differential ADC drivers, SAW filter interfacing and RF/IF gain blocks. It operates over the -40 C to +85 C temperature.
