The LTC6409 fully differential amplifier has 1.1 nV/√Hz noise and -88-dBc distortion. Using a SiGe BiCMOS process, the device features a 10-GHz gain-bandwidth product, 100-dB SFDR to 40 MHz, and 1% settling time of 1.9 nsec. The device drives high-speed ADCs and has an input common-mode range of 0 to 3.5V and an output common-mode range of 0.5 to 3.5V when using a 5V supply. The unity-gain-stable amplifier has an output current as high as 95 mA and operates from a 3 or a 5V supply. Maximum power consumption is 56 mA, and shutdown mode reduces this current to 500 μA. Turn-on time is typically 160 nsec. The device targets use in pulsed-signal applications, such as radar-signal-processing, imaging, high-speed-test-and-measurement, and communications applications. It comes in a 2×3-mm QFN package and operates over the 0 to 70, -40 to +85, and -40 to +125°C temperature ranges. Prices start at $4.50 (1000).
