GENERAL DESCRIPTION
The ADL5580 is a high performance, single-ended or differential amplifier with 10 d B of voltage gain, optimized for applications spanning from dc to 10.0 GHz. The amplifier offers a low referred to input (RTI) noise spectral density (NSD) of 2.24 n V/√Hz (at 1000 MHz) and is optimized for distortion performance over a wide frequency range, making the device an ideal driver for high speed 12-bit to 16-bit analog-to-digital converters (ADCs). The ADL5580 is suited for use in high performance, zero intermediate frequency (IF), and plex IF receiver designs. In addition, this device has low distortion for single-ended input driver applications.
By using two external series resistors, the gain selection from 10 d B for a differential input can be modified to a lower gain. The device maintains low distortion through its output mon-mode voltage (VCM) of 0.5 V, providing a flexible capability for driving ADCs with full-scale levels up to 1.4 V p-p.
