ADS127L18EVM-PDK Evaluation Module
Description
The ADS127L18 is an eight channel, 24-bit,
simultaneous sampling delta-sigma (ΔΣ) analog-to-
digital converter (ADC), supporting data rates up
to 512 kSPS (wideband filter) and data rates up
to 1.365 MSPS (low-latency filter). The ADS127L18
offers excellent ac and dc performance, along with
multiple internal digital filter options. The evaluation
kit includes the ADS127L18EVM board and the
precision host interface (PHI) controller board that
enables the accompanying computer software to
communicate with the ADC over the USB for data
capture, configuration, and analysis.
