AD8335 - Low Cost Variable Gain Amplifier

Datasheet Summary

The AD8335 is a quad variable gain amplifier (VGA) with low noise preamplifier intended for cost and power sensitive applications.

Low noise preamplifier (PrA) Voltage noise = 1.3 nV/√Hz typical Current noise = 2.4 pA/√Hz typical NF = 7 dB (RS = RIN = 50 Ω) Single-ended input; VIN maximum = 625 mV p-p Active input match Input SNR (noise bandwidth = 20 MHz) = 92 dB VGA Differential output VOUT maximum = 5 V p-p, RL = 500 Ω differential Gain range (8 dB output gain step).
10 dB to +38 dB.
low gain mode.
2 dB to +46 dB.
high gain mode Accurate linear-in-dB gain control PrA + VGA performance.
