Analog Devices Unveils AD8369 Amplifier

Analog Devices Inc. (Wilmington, DE) announced the addition of its new AD8369 digitally controlled, variable gain amplifier to its portfolio of high-performance, radio frequency, integrated circuits (RF ICs). It is suitable for use within next-generation 2.5G/3G equipment employing higher and wider dynamic range IF sampling architectures.

The AD8369 is designed for use from low frequencies to 500MHz, and provides a flat-gain response across all gain settings. The device provides a gain-control range from -5dB to +40dB, adjustable in 3dB increments, and controllable through a four-bit digital interface that may be configured in either serial or parallel mode.

The AD8369 is a differential input/differential output device with a high-efficiency output stage that provides low inter-modulation distortion, enabling the part to be used with high-performance, 12-bit, analog-to-digital converters. The AD8369 has been specified for operation within receive-path AGC loops found in cellular base station equipment.

The AD8369 is available in a 16-pin TSSOP package and is rated to work over the industrial temperature range from -40 to +85 degrees C. The AD8369 is priced at $4.20 per unit in 1,000-piece quantities. Samples and production volumes, as well as an evaluation board, are available now.
