User’s Guide
ADS1x48EVM Evaluation Module
ABSTRACT
The ADS1x48 evaluation module (EVM) allows users to evaluate the functionality of the Texas Instruments'
16-bit ADS1148 or the 24-bit ADS1248. ADS1x48 refers to what is common to both devices and EVMs.
Any differences in operation between the devices or EVMs are listed separately. The ADS1x48 devices are
highly integrated delta-sigma ADCs that include a programmable gain amplifier, a 2.048-V voltage reference,
an internal oscillator, dual current sources (IDACs), and several system-monitoring features. Each ADS1x48
device has inputs that can be configured as seven single-ended or four differential inputs. All of these features
integrated into the ADS1x48 devices enable precision measurement for many types of analog temperature
sensors including thermocouples, resistance temperature detectors (RTDs), and thermistors. This user’s guide
describes both the EVM hardware platform and the graphical user interface (GUI) software used to configure
and operate the device. This user’s guide also includes the EVM schematic diagram, board layout, and bill
of materials. The EVM platform eases the evaluation of the ADS1x48 device with hardware, software, and
computer connectivity through the universal serial bus (USB) interface.
Throughout this document, the abbreviation
EVM
and the term
evaluation module
are synonymous with the
