Figure 2. External Clock-Mode Conversion (Mode 0)
Single-ended conversions are internally referenced to
AGND1 (Tables 3 and 4). In differential mode, IN+ and
IN- are selected according to Tables 3 and 5. When
configuring differential channels, the differential pair fol-
lows the analog configuration byte for the positive
channel. For example, to configure CH2 and CH3 for a
±3 x V
configuration byte for a differential conversion with the
±3 x V
for the CH2 and CH3 differential pair, issue the com-
mand 1010 0000.

The MAX1300/MAX1301 input-tracking circuitry has a
2MHz small-signal bandwidth. The 2MHz input band-
width makes it possible to digitize high-speed transient
events. Harmonic distortion increases when digitizing
signal frequencies above 15kHz as shown in the THD
and -SFDR vs. Input Frequency plot in the Typical
Operating Characteristics .
Figure 7 illustrates the software-selectable single-ended
analog input voltage range that produces a valid digital
output. Each analog input channel can be independently
programmed to one of seven single-ended input ranges
by setting the R[2:0] control bits with DIF/SGL = 0.
