Analog Input
The analog input pins of J1 are connected directly to the multiplexer inputs of
the ADC. The detailed electrical specifications of the multiplexer are in the
TLV1570 data sheet, literature number SLAS169.
The board can also be connected to the analog source by using J3. In this
case, the value of R19 is changed to match the required input impedance. If
J3 is not used, R3 should be left open
.
The input range depends on the selected voltage reference. The default is 4 V.
This can be changed by replacing D1 with a Zener diode with the required
reference voltage. As the output buffer of the onboard DAC (TLV5616) has a
gain of 2, the reference voltage is divided by 2 to achieve a matching output
range.
With the default reference, the input range is:
