Analog Devices is sampling two new low-cost ADSP-219x models - the ADSP-2195 and ADSP-2196 - expanding the ADSP-21xx family of code compatible digital signal processors.
The device provides a gain control range from -5 to +40dB, adjustable in 3dB increments, and controllable through a 4bit 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 very low intermodulation distortion, enabling the part to be used with high-performance 12bit analogue-to-digital convertors.
The AD8369 has been specified for operation within receive-path AGC loops found in cellular basestation equipment.
It is ideally suited for use within next generation 2.5G/3G equipment employing higher and wider dynamic range IF sampling architectures.
The AD8369 eases these designs by providing excellent linearity and low noise specifications over gain and bandwidth, plus a user selectable digital interface.
The AD8369 is available in a 16-pin TSSOP package and is rated to work over the industrial temperature range, -40 to +85C.
The AD8369 is priced at $4.20 per unit in 1000-piece quantities.
Samples and production volumes, as well as an evaluation board, are available now.
