The ADS122S14EVM and ADS122C14EVM evaluation modules (EVM) allow users to evaluate the functionality of the ADS122S14 with Serial-Peripheral Interface (SPI) and ADS122C14 with Inter-Integrated Circuit (I2C) interface. These devices are precision, low-power, 8-channel, 24-bit, 64-kSPS Delta-Sigma (ΔΣ) analog to digital converters (ADC) with a flexible input multiplexer and a low-noise programmable gain amplifier (PGA). The EVM kit includes the ADC device and an accompanying precision ADC motherboard (PAMB) used as a USB-to-PC Graphical User Interface (GUI) communication bridge that enables the computer software to communicate with the ADC over the USB for data capture, configuration, and data analysis.
Features
- ADS122S14 or ADS122C14 with 8 independently selectable inputs
- Wide supply range for analog voltage (AVDD) and digital voltage (DVDD)
- Multiple voltage reference options: internal programmable 1.25V or 2.5V voltage reference or external ratiometric reference supplied by the input terminal blocks
- Input terminal blocks that enable easy measurement of many types of analog temperature or bridge sensors
- SPI or I2C interface for communication and configuration
