Dual-Channel Operation
The MAX11102/MAX11103/MAX11106/MAX11111 fea-
ture dual-input channels. These devices use a channel-
select (CHSEL) input to select between analog input AIN1
(CHSEL = 0) or AIN2 (CHSEL = 1). As shown in Figure
15, the CHSEL signal is required to change between the
2nd and 12th clock cycle within a regular conversion to
guarantee proper switching between channels.
14-Cycle Conversion Mode
The ICs can operate with 14 cycles per conversion.
Figure 16 shows the corresponding timing diagram.
Observe that DOUT does not go into high-impedance
mode. Also, observe that tACQ needs to be sufficiently
long to guarantee proper settling of the analog input
voltage. See the Electrical Characteristics table for tACQ
requirements and the Analog Input section for a descrip-
tion of the analog inputs.
Applications Information
Layout, Grounding, and Bypassing
For best performance, use PCBs with a solid ground
plane. Ensure that digital and analog signal lines are
separated from each other. Do not run analog and digital
(especially clock) lines parallel to one another or digital
lines underneath the ADC package. Noise in the VDD
power supply, OVDD, and REF affects the ADC’s perfor-
mance. Bypass the VDD, OVDD, and REF to ground with
0.1FF and 10FF bypass capacitors. Minimize capacitor
lead and trace lengths for best supply-noise rejection.
Choosing an Input Amplifier
It is important to match the settling time of the input
amplifier to the acquisition time of the ADC. The conver-
sion results are accurate when the ADC samples the
input signal for an interval longer than the input signal’s
worst-case settling time. By definition, settling time is
the interval between the application of an input voltage
step and the point at which the output signal reaches
