Description

The ADL5567 is a high performance, dual differential amplifieroptimized for intermediate frequencies (IF) and dc applications.The amplifier offers a low noise of 1.29 nV/?Hz and excellentdistortion performance over a wide frequency range, making itan ideal driver for high speed 16-bit analog-to-digital converters(ADCs). The ADL5567 is ideally suited for use in high performancezero-IF and complex IF receiver designs. In addition, this devicehas excellent low distortion for single-ended input driverapplications.The ADL5567 provides a gain of 20 dB. For the single-ended inputconfiguration, the gain is reduced to 18 dB. Using two externalseries resistors for each amplifier expands the gain flexibility ofthe amplifier and allows for any gain selection from 0 dB to 20 dBfor a differential input and 0 dB to 18 dB for a single-ended input.In addition, this device maintains low distortion down to outputcommon-mode levels of 1.25 V, and therefore providing an addedcapability for driving CMOS ADCs at ac levels up to 2 VP-P.The quiescent current of the ADL5567 using a 5 V supply istypically 74 mA per amplifier in high performance mode.When disabled, each amplifier consumes only 3.5 mA, and has58 dB input to output isolation at 100 MHz.The device is optimized for wideband, low distortion, and lownoise operation, giving it unprecedented performance foroverall spurious-free dynamic range (SFDR). These attributes,together with its adjustable gain capability, make this device theamplifier of choice for driving a wide variety of ADCs, mixers,pin diode attenuators, SAW filters, and multielement discretedevices.Fabricated on an Analog Devices, Inc., high speed silicongermanium (SiGe) process, the ADL5567 is supplied in acompact 4 mm ? 4 mm, 24-lead LFCSP package and operatesover the ?40?C to +85?C temperature.APPLICATIONS Differential ADC drivers Single-ended to differential conversions RF/IF gain blocks SAW filter interfacing
