Product Details

The ADL5567 is a high performance, dual differential amplifier optimized for intermediate frequencies (IF) and dc applications. The amplifier offers a low noise of 1.29 nV/√Hz and excellent distortion performance over a wide frequency range, making it an ideal driver for high speed 16-bit analog-to-digital converters (ADCs). The ADL5567 is ideally suited for use in high performance zero-IF and complex IF receiver designs. In addition, this device has excellent low distortion for single-ended input driver applications.

The ADL5567 provides a gain of 20 dB. For the single-ended input configuration, the gain is reduced to 18 dB. Using two external series resistors for each amplifier expands the gain flexibility of the amplifier and allows for any gain selection from 0 dB to 20 dB for a differential input and 0 dB to 18 dB for a single-ended input. In addition, this device maintains low distortion down to output common-mode levels of 1.25 V, and therefore providing an added capability for driving CMOS ADCs at ac levels up to 2 VP-P.

The quiescent current of the ADL5567 using a 5 V supply is typically 74 mA per amplifier in high performance mode. When disabled, each amplifier consumes only 3.5 mA, and has 58 dB input to output isolation at 100 MHz.

The device is optimized for wideband, low distortion, and low noise operation, giving it unprecedented performance for overall spurious-free dynamic range (SFDR). 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 silicon germanium (SiGe) process, the ADL5567 is supplied in a compact 4 mm × 4 mm, 24-lead LFCSP package and operates over the −40°C to +85°C temperature.

APPLICATIONS

  • Differential ADC drivers
  • Single-ended to differential conversions
