Quad-Channel, Ultra-Low-Noise Amplifier with
Digitally Programmable Input Impedance
Typical Operating Characteristics
(MAX2034 Typical Application Circuit, V_CC = +4.75V to +5.25V, source impedance R_S = 200Ω, PD = 0, D2/D1/D0 = 0/1/0 (R_IN = 200Ω),
signal AC-coupled to IN_, INB_ is AC grounded, V_OUT is the differential output between OUT_+ and OUT_-, f_{IN_} = 5MHz, R_L = 200Ω
between the differential outputs, C_L = 20pF from each output to ground, T_A = 0°C to +70°C, unless otherwise specified.)
