ADL5565
RECOMMENDED FOR NEW DESIGNS6 GHz Ultrahigh Dynamic Range Differential Amplifier
Part Details
- 3 dB bandwidth of 6 GHz (AV = 6 dB)
- Pin strappable gain adjust: 6 dB, 12 dB, and 15.5 dB
- Gain range from 0 dB to 15.5 dB using two external resistors
- Low noise input stage: NF = 8.7 dB at 15.5 dB gain
- Differential or single-ended input to differential output
- IMD3 of −112 dBc at 100 MHz center
- Slew rate: 11 V/ns
- See datasheet for additional features
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 external series resistors expands the gain flexibility of the amplifier and allows for any gain selection from 0 dB to 15.5 dB for a differential input and 0 dB to 13 dB for a single-ended input.
The quiescent current of the ADL5565 is typically 70 mA, and when disabled, consumes less than 5 mA with −25 dB of input-to-output isolation at 100 MHz.
The device is optimized for wideband, low distortion, and noise performance, giving it unprecedented performance for overall spurious-free dynamic range. These attributes, together with its adjustable gain capability, make this device the amplifier of choice for driving a wide variety of ADCs, mixers, pin diode attenuators, SAW filters, and multielement discrete devices.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADL5565 is supplied in a compact 3 mm × 3 mm, 16-lead LFCSP package and operates over the −40°C to +85°C temperature range.

ADIsimPLL™
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
Open ToolADIsimRF
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
Open ToolSys-Parameter Models for Keysight Genesys
Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.
