Temperature Monitoring Using BOOSTXL-ADS7142-Q1
The BOOSTXL-ADS7142-Q1 has a provision for an onboard NTC-based temperature monitoring circuit.
By default, the NTC monitoring section is not populated. The NTC-based temperature monitoring can be
enabled on CH0. In order to enable temperature monitoring, make the changes to the evaluation board as
shown in
.

Input Signal Conditioning Block on the BOOSTXL-ADS7142-Q1
For applications where the input signal requires additional conditioning before being interfaced to the ADC,
the BOOSTXL-ADS7142-Q1 has an optional signal conditioning path that can be populated between the
input signal and the ADS7142-Q1. The board has a provision to introduce a dual-channel operational
amplifier (U4) which can be configured in either a non-inverting buffer or inverting gain configuration based
on the signal conditioning requirement. By default, this signal conditioning block is not populated on the
evaluation board. In order to use this block, populate the operational amplifier U4 and the associated
biasing components based on the required op-amp configuration (non-inverting buffer or inverting
configuration). See
for more details.
