Power down Fabricated using the high speed XFCB3 SiGe process APPLICATIONS Differential ADC drivers Single-ended-to-differential conversion RF/IF gain blocks SAW filter interfacing GENERAL DESCRIPTION The ADL5565 is a high performance differential amplifier The quiescent current of the ADL5565 is typically 70 mA, and optimized for RF and IF applications. The amplifier offers low when disabled, consumes less than 5 mA with 25 dB of input- noise of 1.5 nV/Hz and excellent distortion performance over to-output isolation at 100 MHz. a wide frequency range making it an ideal driver for high speed The device is optimized for wideband, low distortion, and noise 8-bit to 16-bit analog-to-digital converters (ADCs). performance, giving it unprecedented performance for overall The ADL5565 provides three gain levels of 6 dB, 12 dB, and spurious-free dynamic range. These attributes, together with its 15.5 dB through a pin strappable configuration. For the single- adjustable gain capability, make this device the amplifier of ended input configuration, the gains are reduced to 5.3 dB, choice for driving a wide variety of ADCs, mixers, pin diode 10.3 dB, and 13 dB. Using two external series resistors expands attenuators, SAW filters, and multielement discrete devices. the gain flexibility of the amplifier and allows for any gain Fabricated on an Analog Devices, Inc., high speed SiGe process, selection from 0 dB to 15.5 dB for a differential input and 0 dB the ADL5565 is supplied in a compact 3 mm 3 mm, 16-lead to 13 dB for a single-ended input. LFCSP package and operates over the 40C to +85C temperature range. Rev. G Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
