The AD8350 series are high performance fully-differential amplifiers useful in RF and IF circuits up to 1000 MHz. The amplifier has excellent noise figure of 5.9 dB at 250 MHz. It offers a high output third order intercept (OIP3) of +28 dBm at 250 MHz. Gain versions of 15 dB and 20 dB are offered. The AD8350 is designed to meet the demanding requirements of high performance, low noise, single supply, differential amplifiers.
The AD8350 is a high‑performance differential amplifier designed for RF and IF applications up to 1 GHz. It provides a low noise figure, high output third‑order intercept (OIP3), and can operate from a single 5 V to 10 V supply while drawing only 28 mA.
The device is available in two gain versions (15 dB and 20 dB) and packaged in 8‑lead SOIC or micro‑SOIC. Detailed specifications include bandwidth, gain, noise, power‑supply characteristics, and absolute maximum ratings. Application notes describe basic single‑ended and differential connections, as well as reactive matching techniques.
