The ADL5562 is a high performance differential amplifier The device is optimized for wideband, low distortion optimized for RF and IF applications. The amplifier offers low performance. These attributes, together with its adjustable gain noise of 2.1 nV/√Hz and excellent distortion performance over capability, make this device the amplifier of choice for general- a wide frequency range, making it an ideal driver for high speed purpose IF and broadband applications where low distortion, 8-bit to 16-bit ADCs. noise, and power are critical. This device is optimized for the The ADL5562 provides three gain levels of 6 dB, 12 dB, and best combination of slew speed, bandwidth, and broadband 15.5 dB through a pin-strappable configuration. For the single- distortion. These attributes allow it to drive a wide variety of ended input configuration, the gains are reduced to 5.6 dB, analog-to-digital converters (ADCs) and make it ideally suited 11.1 dB, and 14.1 dB. Using an external series input resistor for driving mixers, pin diode attenuators, SAW filters, and expands the amplifier gain flexibility and allows for any gain multi-element discrete devices. selection from 0 dB to 15.5 dB. Fabricated on an Analog Devices, Inc., high speed SiGe process, The quiescent current of the ADL5562 is typically 80 mA and, the ADL5562 is supplied in a compact 3 mm × 3 mm, 16-lead when disabled, consumes less than 3 mA, offering excellent LFCSP package and operates over the temperature range of input-to-output isolation. −40°C to + 85°C.
