2.2 Design Considerations

Some of the key considerations during the design of TIDA-00454 include:

• ADC to use for measurement : External or Internal to MCU, SAR or delta-sigma, 16-bit or 24-bit
• DC analog output: Isolation – digital or optocoupler, basic isolation or reinforced isolation, channel-channel isolation or group isolation, DAC with external voltage or current driver or DAC with internal voltage or current output
• Interface to DAC: Serial interface – I²C or SPI
• ADC sampling rate and DAC data-refresh rate
• Relay output with zero-cross reference
