Measure AIN0 (Channel0) Voltage
This section describes the steps involved in selecting and measuring AIN0 (Channel0) voltage:
1. Make sure following shunt is in place on the BOOSTXL-ADS7841-Q1 EVM: J13 between 2 and 3
(select VREF = 4.5V)
2. Connect J10.1 to J1.1 (3.3V) by a jumper wire.
3. Select "Samples" as 4096, set "SCLK" as 1000 (KHz), and set "Sample Rate" as 10 (KHz).
4. Make sure "Selected Channel" is Channel0, "Single/Diff" is selected as Single, and "Power Down" is
Always On as shown in
below.
5. Press “Collect”.
6. Min Code, Max Code, Min Volt (V), Max Volt (V) read out are displayed as shown in
.
