APPLICATIONS Differential ADC drivers Single-ended-to-differential conversion RF/IF gain blocks SAW filter interfacing www.DataSheet.co.kr GENERAL DESCRIPTION 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 e...
