GENERAL DESCRIPTION
The ADL5566 is a high performance, dual differential amplifier The quiescent current of the ADL5566, using a 3.3 V supply, is optimized for IF and dc applications. The amplifier offers low typically 70 mA per amplifier. When disabled, it consumes less noise of 1.3 nV/√Hz and excellent distortion performance over than 3.5 mA per amplifier and has −25 dB of input-to-output a wide frequency range, making it an ideal driver for high speed isolation at 100 MHz. 16-bit analog-to-digital converters (ADCs). The ADL5566 is The device is optimized for wideband, low distortion, and noise ideally suited for use in high performance, zero IF/complex performance, giving it unprecedented performance for overall IF receiver designs. In addition, this device has excellent low spurious-free dynamic range (SFDR). These attributes, together distortion for single-ended input drive applications. with its adjustable gain capability, make this device the amplifier The ADL5566 provides a gain of 16 dB. For the single-ended input of choice for driving a wide variety of ADCs, mixers, pin diode configuration, the gain is reduced to 14 dB. Using two external attenuators, SAW filters, and multi-element discrete devices. series resistors for each amplifier expands the gain flexibility of Fabricated on an Analog Devices, Inc., high speed SiGe process, the the amplifier and al ows for any gain selection from 0 dB to 16 dB ADL5566 is supplied in a compact 4 mm × 4 mm, 24-lead LFCSP for a differential input and 0 dB to 14 dB for a single-ended input. package and operates over the −40°C to +85°C temperature range. In addition, this device maintains low distortion down to output (VOCM) levels of 1.2 V providing an added capability for driving CMOS ADCs at ac levels up to 2 V p-p.
