As a result, the analog input impedance is relatively
constant over the input voltage as shown in Figure 5.
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 con-
figuring differential channels, the differential pair follows
the analog configuration byte for the positive channel.
For example, to configure CH2 and CH3 for a ±VREF dif-
ferential conversion, set the CH2 analog configuration
byte for a differential conversion with the ±VREF range
(1010 1100). To initiate a conversion for the CH2 and
CH3 differential pair, issue the command 1010 0000.
Analog Input Bandwidth
The MAX1302 input-tracking circuitry has a 1.5MHz
small-signal bandwidth. The 1.5MHz input bandwidth
makes it possible to digitize high-speed transient events.
Harmonic distortion increases when digitizing signal fre-
quencies above 15kHz as shown in the -SFDR, THD vs.

Characteristics.
Analog Input Range and Fault Tolerance
Figure 7 illustrates the software-selectable single-
ended analog input voltage range that produces a valid
digital output. Each analog input channel can be inde-
pendently programmed to one of seven single-ended
input ranges by setting the R[2:0] control bits with
DIF/SGL = 0.
