The ADL5569 is a high performance, dual, differential amplifier with 20 dB of voltage gain, optimized for applications spanning from dc to 6.5 GHz. The amplifier is available in a dual format, and it offers a low referred to input (RTI) noise spectral density (NSD) of 1.0 nV/√Hz (at 100 MHz) and excellent distortion performance over a wide frequency range, making it an ideal driver for high speed 12-bit to 16-bit analog-to-digital converters (ADCs). The ADL5569 is ideally suited for use in high performance zero intermediate frequency (IF) and complex IF receiver designs. In addition, this device has excellent low distortion for single-ended input driver applications.

Using two external series resistors for each amplifier expands the gain flexibility of the amplifier and allows any gain selection from 6 dB to 20 dB for a differential input. For a single-ended input, the gain can be adjusted from 6 dB to 17 dB with the addition of some external resistors. This device maintains low distortion through its output common-mode range of 2.0 V to 3.0 V, providing a flexible capability for driving ADCs with ac levels up to 2 V_P-P.

Operating from a single 5 V supply, the quiescent current of the ADL5569 is typically 86 mA per amplifier. When disabled, the amplifiers consume only 8 mA per amplifier.

The device is optimized for wideband, low distortion, and low noise operation, giving it unprecedented second harmonic distortion (HD2) and third harmonic distortion (HD3) from dc to 4 GHz. 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, surface acoustic wave (SAW) filters, and a multitude of discrete radio frequency (RF) devices.

Fabricated on an Analog Devices, Inc., high speed silicon germanium (SiGe) process, the ADL5569 is supplied in a compact 2.5 mm × 3 mm, 16-lead LFCSP package and operates over the −40°C to +85°C temperature range.

Product Details

The evaluation board is powered by a single 5 V supply. The power supply is decoupled by 10 µF and 0.1 µF capacitors. On board regulators provide a 2.5 V common mode voltage and 3 V logic supply voltage to enable/disable the power-down feature.

Several termination options are also provided to allow the user to terminate unused inputs/outputs of the amplifier for single-ended applications.
