VCA2616 Datasheet, PDF (8/23 Pages) TEXAS ADVANCED OPTOELECTRONIC SOLUTIONS – Dual, Variable-Gain Amplifier with Low-Noise Preamp

TYPICAL CHARACTERISTICS (Cont.)
At T_A = +25°C, V_DDA = V_DDB = V_DDR = +5V, load resistance = 500Ω on each output to ground, MGS = 011, LNP = 22dB and f_IN = 5MHz, unless otherwise noted.
The input to the preamp (LNP) is single-ended, and the output from the VCA is single-ended, unless otherwise noted. This results in a 6dB reduction in signal
amplitude compared to differential operation.
