AD8370AREZ-RL7 Datasheet PDF - ADI

●Product Details

●The AD8370 is a high performance, digitally controlled variable gain amplifier, designed to be used at IF frequencies within communication infrastructure equipment.

●The part provides two gain control ranges that are controlled through a three wire digital interface, and allow the user to attain fine gain control for maximum receiver sensitivity.

●The AD8370 has been fully specified for operation at common wireless IF frequencies 70 / 140 / 190 / 240 / 380MHz. The high output compression and fine gain control adjustability makes the AD8370 an ideal choice for to be used within digital receiver AGC circuits for GSM / CDMA2000 / W-CDMA cellular base stations.

●The AD8370 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 –40 to +85 C temperature range.

● Availability

●Samples AD8370ARU and an evaluation boards AD8370-EVAL are available.
