TIDA-00835 High Accuracy ±0.5% Current and Isolated Voltage Measurement Ref Design Using 24-Bit Delta-Sigma ADC | TI.com
TIDA-00835: The TIDA-00835 reference design allows for accurate voltage and current measurement using a bipolar input configuration by incorporating a four- channel, 24-bit simultaneously-sampling differential input Delta-Sigma ADC over wide dynamic range. The ADC is configured to measure ±2.5 V bipolar input. The inputs are scaled to ADC measurement range of ±2.5V using a fixed gain amplifier. This AFE chains two ADCs together using a common external clock to expand the number of input channels to eight while simultaneously sampling all of the input channels. By having more measurement channels per module, overall system cost is reduced.
TIDA-00493 Voltage & Current (Power) Measurement AFE for mV Output Sensor Interface to SAR ADC Reference Design | TI.com
TIDA-00493: The TIDA-00493 TI design is a fixed gain amplifier stage for measuring low amplitude voltage and current inputs accurately over a wide dynamic range using SAR ADC for power measurement applications. Low-amplitude AC voltage from voltage dividers, current transformers or split core current sensors with a 333-mV output can be accurately measured.
TIDA-00810 Reference Design to Measure AC Voltage & Current in Protection Relays w/Delta-Sigma Chip Diagnostics | TI.com
TIDA-00810: The TIDA-00810 reference design accurately measures analog inputs performance and includes chip diagnostics to help identify power systems failures early by using a highly accuracy AC voltage and current measurement analog front end (AFE) and a four-channel, 24-bit simultaneously-sampling differential input Delta-Sigma ADC for measurement over wide dynamic range. The ADC is configured to measure 0-5 V unipolar. The inputs are scaled to ADC measurement range using a fixed gain amplifier with 2.5 V DC output level shift. The AFE can be used to measure output of a current transformer, potential divider with analog isolation and Rogowski active integrator. The AFE uses 10-Bit low resolution successive approximation register (SAR) ADC in parallel with a 24 bit ∑-∆ ADC for ADS131A04 diagnostics.
