Texas Instruments ADS127L18 | Demoboard ADS127L18EVM-PDK

Beschreibung

The ADS127L18 is an eight channel, 24-bit, simultaneous sampling delta-sigma (ΔΣ) analog-todigital 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.
