Digitally Programmable Input Impedance

Typical Operating Characteristics (continued)

(MAX2034 Typical Application Circuit, VCC = +4.75V to +5.25V, source impedance RS = 200Ω, PD = 0, D2/D1/D0 = 0/1/0 (RIN = 200Ω),

signal AC-coupled to IN_, INB_ is AC grounded, VOUT is the differential output between OUT_+ and OUT_-, fIN_ = 5MHz, RL = 200Ω

between the differential outputs, CL = 20pF from each output to ground, TA = 0°C to +70°C, unless otherwise specified.)
