GENERAL DESCRIPTION

The AD8352 is a high performance differential amplifier optimized for RF and IF applications. It achieves better than 80 dB SFDR performance at frequencies up to 200 MHz, and 65 dB beyond 500 MHz, making it an ideal driver for high speed 12-bit to 16-bit analog-to-digital converters (ADCs).

Single resistor gain adjust: 3 dB ≤ AV ≤ 25 dB

Single resistor and capacitor distortion adjust

Input resistance: 3 kΩ, independent of gain (AV)

Differential or single-ended input to differential output

Low noise input stage: 2.7 nV/√Hz RTI at AV = 10 dB

Low broadband distortion

10 MHz: −86 dBc HD2, −82 dBc HD3

70 MHz: −84 dBc HD2, −82 dBc HD3

190 MHz: −81 dBc HD2, −87 dBc HD3
