The device features a 4-bit digitally controlled gain control interface configurable for either parallel or 3 wire serial control. The gain control range spans 45dB adjustable in 3dB increments.

The AD8369 is ideally suited to be used in digital IF receivers and is fully specified for operation at common IF frequencies 70/140/190/240/380MHz. The gain stability and flatness is below 0.1dB over a 20MHz channel bandwidth at 380MHz. Coupled with the low distortion and the ability to drive 200 or 1K, the AD8369 allows optimal placement and flexibility as a high IF gain control element.

The AD8369 is fabricated on an advanced silicon bipolar process, operating on a single 3 or 5 volt supply, packaged in space saving 16-lead thin shrunk small outline (TSSOP) package and fully specified over the –40ºC to +85ºC temperature range.
