ADS1263EVM-PDK Evaluation Module
This user's guide describes the characteristics, operation, and use of the
This EVM is an evaluation platform for the Texas Instruments ADS1263, a low-noise, 32-bit, 38-kSPS,
10-channel (multiplexed), delta-sigma (ΔΣ) analog-to-digital converter (ADC). The highly-integrated ADS1263
includes a programmable gain amplifier (PGA), a 2.5-V low-drift voltage reference, an internal oscillator,
dual-sensor excitation current sources (IDAC), several system-monitoring features, and an auxiliary 24-bit
ΔΣ ADC. The integrated features and excellent performance of the ADS1263 enable precision measurement
of strain gauges, weigh scales, pressure sensors, thermocouples, thermistors, and resistance temperature
detectors (RTDs). The ADS1263EVM eases the evaluation of the device with hardware, software, and computer
connectivity through the universal serial bus (USB) interface. This user's guide includes complete circuit
descriptions, schematic diagrams, and a bill of materials. Throughout this document, the abbreviation EVM
and the term evaluation module are synonymous with the ADS1263EVM.
The ADS1263EVM and software can also support the ADS1262, which is identical to the ADS1263
except that the ADS1262 does not include the auxiliary 24-bit ΔΣ ADC. However, the user must
manually remove the ADS1263 and install the ADS1262. See
ADS1263 on the EVM. The ADS1262 is not discussed further in this document.
