The ADL5580 is a high performance, single-ended or differential amplifier with 10 dB 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 nV/√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 complex 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 dB for a differential input can be modified to a lower gain. The device maintains low distortion through its output common-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.
Operating from a +5 V and −1.8 V supply, the positive and negative supply current of the ADL5580 is typically +276 mA and −224 mA, respectively. The device has a power disable feature, and when disabled, the amplifier consumes 2 mA.
The ADL5580 is optimized for wideband, low distortion, and low noise operation at the dc to 10.0 GHz frequency range. These attributes, together with its adjustable gain capability, make this device an optimal choice for driving a wide variety of ADCs, mixers, pin diode attenuators, surface acoustic wave (SAW) filters, and a multiplicity of discrete RF devices.
Fabricated on an Analog Devices, Inc., high speed silicon germanium (SiGe) process, the ADL5580 is supplied in a compact 4 mm × 4 mm, 20-terminal land grid array (LGA)
package and operates over the −40°C to +85°C temperature range.
