ADA4960-1

低失真超高速差分ADC驱动器 Low Distortion Ultrahigh Speed Differential ADC Driver

GENERAL DESCRIPTION

The is a high performance differential amplifier optimized for RF and IF applications. It achieves better than 63dB SFDR performance at frequencies up to 500 MHz, and 52dB up to 1GHz, making it an ideal driver for high speed 8-bit to 10-bit giga-sample analog-to-digital converters ADCs.
