mode, even-order harmonics are lower as both inputs
(IAP, IAN, QAP, QAN) are balanced, and each of the
Rx ADC inputs only requires half the signal swing com-
pared to single-ended mode. Figure 11 shows an RF
transformer converting the MAX19711 Tx DAC differen-
tial analog outputs to single-ended.
Using Op-Amp Coupling
Drive the MAX19711 Rx ADC with op amps when a
balun transformer is not available. Figures 12 and 13
show the Rx ADC being driven by op amps for AC-cou-
pled single-ended and DC-coupled differential applica-
tions. Amplifiers such as the MAX4454 and MAX4354
provide high speed, high bandwidth, low noise, and
low distortion to maintain the input signal integrity. The
op-amp circuit shown in Figure 13 can also be used to
interface with the Tx DAC differential analog outputs to
provide gain or buffering. The Tx DAC differential ana-
log outputs cannot be used in single-ended mode
because of the internally generated common-mode
level. Also, the Tx DAC analog outputs are designed to
drive a differential input stage with input impedance
