ADI Wideband Differential Amplifier Drives High Frequency A/D Converters

The new amplifier is an ideal solution for applications where high linearity and low noise are critical, including IF sampling receivers in wireless infrastructure equipment, industrial instrumentation and defence electronics.

The ADL5566 differential amplifier supports detailed specifications at the following frequencies: 70 MHz, 100 MHz, 140 MHz, 250 MHz, 500 MHz, and 1000 MHz, thereby simplifying the design process and enabling a highly flexible design that can reduce time to market, bill of materials costs and board space. Its best-in-class frequency distortion and noise level performance allow system designers to continue increasing bandwidth and dynamic range for high-performance receiver designs. In addition, the ADL5566 differential amplifier drives best in class high-speed converters, including ADI’s new 16-bit 250-MSPS AD9467 analog-to-digital converter, with little or no impact on overall system performance.

ADL5566 Differential Amplifier Key Features:
