High Accuracy ?0.5% Current and Isolated Voltage Measurement Ref Design Using 24-Bit Delta-Sigma ADC (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.

Возможности

Precision data acquisition over wide input range using 4-channel, simultaneous sampling, 24-Bit ∑-∆ ADCs Channel expansion by chaining multiple devices and simultaneous sampling by synchronizing with a buffered common clock Current measurement – performance verified using current transformer or Rogowski coil with hardware integrator Voltage measurement – performance verified using potential divider (PD) without and with an isolation amplifier (basic or reinforced isolation)
