Description

The ADL5561 is a high performance differential amplifier optimized for RF and IF applications. The amplifier offers low noise of 2.1 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 ADL5561 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 5.6 dB, 11.1 dB, and 14.1 dB. Using an external series input resistor expands the amplifier gain flexibility and allows for any gain selection from 0 dB to 15.5 dB.The quiescent current of the ADL5561 is typically 40 mA and, when disabled, consumes less than 3 mA, offering excellent input-to-output isolation.The device is optimized for wideband, low distortion performance. These attributes, together with its adjustable gain capability, make this device the amplifier of choice for general-purpose IF and broadband applications where low distortion, noise, and power are critical. This device is optimized for the best combination of slew speed, bandwidth, and broadband distortion. These attributes allow it to drive a wide variety of ADCs and make it ideally suited for driving mixers, pin diode attenuators, SAW filters, and multi-element discrete devices.Fabricated on the Analog Devices, Inc., high speed SiGe process, the ADL5561 is supplied in a compact 3 mm ? 3 mm, 16-lead LFCSP package and operates over the temperature range of ?40?C to +85?C.Applications Differential ADC drivers Single-ended-to-differential conversion RF/IF gain blocks SAW filter interfacing
