GENERAL DESCRIPTION
The ADL5569 is a high performance, dual, differential amplifier 3.0 V, providing a flexible capability for driving ADCs with ac with 20 dB of voltage gain, optimized for applications spanning levels up to 2 V p-p. from dc to 6.5 GHz. The amplifier is available in a dual format, Operating from a single 5 V supply, the quiescent current of the and it offers a low referred to input (RTI) noise spectral density ADL5569 is typically 86 mA per amplifier. When disabled, the (NSD) of 1.0 nV/√Hz (at 100 MHz) and excel ent distortion amplifiers consume only 8 mA per amplifier. performance over a wide frequency range, making it an ideal driver for high speed 12-bit to 16-bit analog-to-digital The device is optimized for wideband, low distortion, and low converters (ADCs). The ADL5569 is ideal y suited for use in noise operation, giving it unprecedented second harmonic high performance zero intermediate frequency (IF) and distortion (HD2) and third harmonic distortion (HD3) from complex IF receiver designs. In addition, this device has dc to 4 GHz. These attributes, together with its adjustable gain excellent low distortion for single-ended input driver capability, make this device the amplifier of choice for driving a applications. wide variety of ADCs, mixers, pin diode attenuators, surface acoustic wave (SAW) filters, and a multitude of discrete radio Using two external series resistors for each amplifier expands frequency (RF) devices. the gain flexibility of the amplifier and al ows any gain selection from 6 dB to 20 dB for a differential input. For a single-ended Fabricated on an Analog Devices, Inc., high speed silicon input, the gain can be adjusted from 6 dB to 17 dB with the germanium (SiGe) process, the ADL5569 is supplied in a addition of some external resistors. This device maintains low compact 2.5 mm × 3 mm, 16-lead LFCSP package and operates distortion through its output common-mode range of 2.0 V to over the −40°C to +85°C temperature range.
