Product Details
The ADL5565 is a high performance differential amplifier optimized for RF and IF applications. The amplifier offers low noise of 1.5 nV/√Hz and excellent distortion performance over a wide frequency range making it an ideal driver for high speed 8-bit to 16-bit analog-to-digital converters (ADCs).
The ADL5565 provides three gain levels of 6 dB, 12 dB, and 15.5 dB through a pin strappable configuration. For the single-ended input configuration, the gains are reduced to 5.3 dB, 10.3 dB, and 13 dB. Using two external series resistors expands the gain flexibility of the amplifier and allows for any gain selection from 0 dB to 15.5 dB for a differential input and 0 dB to 13 dB for a single-ended input.
The quiescent current of the ADL5565 is typically 70 mA, and when disabled, consumes less than 5 mA with −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. 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 multielement discrete devices.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADL5565 is supplied in a compact 3 mm × 3 mm, 16-lead LFCSP package and operates over the −40°C to +85°C temperature range.
