SBOS520B â JULY 2010 â REVISED JANUARY 2012
TYPICAL CHARACTERISTICS (continued)
At TA = +25°C, VS+ = +5V, VOCM = +2.5V, VOUT = 2VPP, RL = 400Ω differential, G = +6dB, differential input and output, and
input and output pins referenced to midsupply, unless otherwise noted. Measured using EVM as discussed in Test Circuits
section.
