The TIDA-01333 isolated high voltage analog input module reference design has eight channels supporting both, voltage and current measurement. In addition, 4 channels support common-mode voltages up to ±160V. Isolation of +5V line and the Serial Peripheral Interface (SPI) communication is done in a single chip using the ISOW7841. The design uses ADS8681 which is a 16-bit analog to digital converter (ADC) that can handle input voltages up to ±12.288V. This makes unnecessary any preprocessing of standard input voltages in the industrial space.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
