ADL5566:  4.5 GHz Ultrahigh Dynamic Range, Dual Differential Amplifier

Product Details

Product Status:Recommended for New Designs

The ADL5566 is a high performance, dual differential amplifier optimized for IF and dc applications. The amplifier offers low noise of 1.3 nV/√Hz and excellent distortion performance over a wide frequency range, making it an ideal driver for high speed 16-bit analog-to-digital converters (ADCs). The ADL5566 is ideally suited for use in high performance, zero IF/complex IF receiver designs. In addition, this device has excellent low distortion for single-ended input drive applications.

The ADL5566 provides a gain of 16 dB. For the single-ended input configuration, the gain is reduced to 14 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 16 dB for a differential input and 0 dB to 14 dB for a single-ended input. 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.

The quiescent current of the ADL5566, using a 3.3 V supply, is typically 70 mA per amplifier. When disabled, it consumes less than 3.5 mA per amplifier and has −25 dB of input-to-output isolation at 100 MHz.

The device is optimized for wideband, low distortion, and noise performance, giving it unprecedented performance for overall spurious-free dynamic range (SFDR). These attributes, together with its adjustable gain capability, make this device the amplifier of choice for driving a wide variety of ADCs, mixers, pin diode attenuators, SAW filters, and multi-element discrete devices.

Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADL5566 is supplied in a compact 4 mm × 4 mm, 24-lead LFCSP package and operates over the −40°C to +85°C temperature range.
