Analog Devices’ Wideband Dual Differential Amplifier Drives High Frequency A/D Converters with Industry’s Best Distortion and Noise Performance

Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications and RF ICs, today introduced a dual-channel differential amplifier for driving high speed 12- to 18-bit A/D converters. Featuring a 3dB bandwidth of 4.5 GHz, the ADL5566 differential amplifier is optimized for wideband, high IF (intermediate frequency), low distortion, and noise performance out to 500 MHz. At 100 MHz, this device achieves an IP3 (third order intercept) and IP2 (second order intercept) of 51 dBm and 100 dBm. The ADL5566 differential amplifier is ideal for high linearity and low noise applications, including IF sampling receivers in wireless infrastructure equipment, industrial instrumentation and defense electronics. This new device is also an ideal solution for general purpose applications where the device delivers comparable single ended (input drive) distortion performance.

The ADL5566 differential amplifier supports detailed specifications at the following frequencies: 70 MHz, 100 MHz, 140 MHz, 250 MHz, 500 MHz, and 1000 MHz. Its best-in-class frequency distortion and noise level performance simplifies AAF (anti-aliasing filter) designs and allow system designers to continue increasing bandwidth and dynamic range for receivers with little or no impact on overall system performance.

ADL5566 Differential Amplifier Key Features:

  • High intercept power linearity: OIP3/OIP2 46 dBm/82.6 dBm at 200 MHz (16 dB gain)
  • 2nd/3rd order distortion levels (2 Vpp into 200 ohms): –94.5 dBc/ –87.2 dBc at 200 MHz (16 dB gain)
  • RTI noise: 1.3 nV/√ HZ (16dB gain)
  • Support single-ended and differential-input application
  • Power consumption: 70 mA per channel at 3.3 V and 80 mA per channel at 5 V
  • Power supply range: 2.8 V to 5.2 V with channel independent enable function
