Data Sheet
FEATURES
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 −3 dB bandwidth of 85 MHz Excellent overload performance Supply: 5 V Power consumption 95 mW/channel (380 mW total) 65 mW/channel (PrA off; 260 mW total) Power-down
