As shown in Figure 11, drive the MAX1391/MAX1394
chip-select input (CS) with the DSP’s frame-sync signal.
OE may be connected to GND or driven independently.
For continuous conversion operation, keep OE low and
make the CS falling edge coincident with the 16th
falling edge of the SCLK.
Unregulated Two-Cell or Single Lithium
LiMnO2 Cell Operation
Low operating voltage (1.5V to 3.6V) and ultra-low-power
consumption make the MAX1391/MAX1394 ideal for low
cost, unregulated, battery-powered applications without
the need for a DC-DC converter. Power the MAX1391/
MAX1394 directly from two alkaline/NiMH/NiCd cells in
series or a single lithium coin cell as shown in the
Typical
Operating Circuit.
Fresh alkaline cells have a voltage of approximately
1.5V per cell (3V with 2 cells in series) and approach
end of life at 0.8V (1.6V with 2 cells in series). A typical
2 x AA alkaline discharge curve is shown in Figure 12a.
A typical CR2032 lithium (LiMnO2) coin cell discharge
curve is shown in Figure 12b.
Layout, Grounding, and Bypassing
For best performance, use PCBs. Board layout must
ensure that digital and analog signal lines are separat-
ed from each other. Do not run analog and digital
(especially clock) lines parallel to one another, or digital
lines underneath the ADC package.
Figure 13 shows the recommended system ground
connections. Establish a single-point analog ground
(star ground point) at the MAX1391/MAX1394s’ GND
pin or use the ground plane.
High-frequency noise in the power supply (VDD)
degrades the ADC’s performance. Bypass VDD to GND
with a 0.1F capacitor as close to the device as possi-
ble. Minimize capacitor lead lengths for best supply
noise rejection. To reduce the effects of supply noise, a
10
Ω resistor can be connected as a lowpass filter to
attenuate supply noise.
Exposed Pad
The MAX1391/MAX1394 TDFN package has an
exposed pad on the bottom of the package. This pad is
not internally connected. Connect the exposed pad to
the GND pin on the MAX1391/MAX1394 or leave float-
ing for proper electrical performance.
Definitions
Integral Nonlinearity (INL)
INL is the deviation of the values on an actual transfer
function from a straight line. For the MAX1391/
MAX1394, this straight line is between the end points of
the transfer function once offset and gain errors have
been nullified. INL deviations are measured at every
step and the worst-case deviation is reported in the
Electrical Characteristics section.
