MAX1193
In idle mode, the pipeline ADCs, reference, and clock
distribution circuits are powered, but the outputs are
forced to tri-state. The wake-up time from idle mode is
dominated by the 5ns required for the output drivers to
start from tri-state. When the outputs transition from tri-
state to on, the last converted word is placed on the
digital outputs.
In the normal operating mode, all sections of the
MAX1193 are powered.
Applications Information
The circuit of Figure 7 operates from a single 3V supply
and accommodates a wide 0.5V to 1.5V input common-
mode voltage range for the analog interface between
an RF quadrature demodulator (differential, DC-cou-
pled signal source) and a high-speed ADC.
Furthermore, the circuit provides required SINAD and
SFDR to demodulate a wideband (BW = 3.84MHz),
QAM-16 communication link. RISO isolates the op amp
output from the ADC capacitive input to prevent ringing
and oscillation. CIN filters high-frequency noise.
