Frequently Asked Questions
What resolution and linearity does ADS8328IPWG4 provide for precision sensor measurement?
The ADS8328IPWG4 offers 16-bit resolution with a maximum linearity error of 0.0046%, corresponding to less than 0.3 LSB at full scale. This level of accuracy is suitable for measuring strain gauges, RTD temperature sensors, and pressure transducers where small signal differences must be resolved without calibration offsets masking genuine measurement changes.
How fast can ADS8328IPWG4 sample, and which dynamic signal applications does this support?
With a maximum conversion time of 1.636 µs, the ADS8328IPWG4 supports throughput rates up to approximately 500 kSPS. This is adequate for audio frequency analysis up to 200 kHz bandwidth, vibration monitoring of rotating machinery, and multi-channel power quality measurement where fast per-channel sampling is needed across 2 inputs.
What analog input voltage range does ADS8328IPWG4 accept, and how should the reference be set for a 0V to 2.5V signal?
The ADS8328IPWG4 accepts analog input voltages up to 2.525V referenced to its VREF input. For a 0V to 2.5V sensor signal, an external 2.5V reference such as the REF5025 can be tied to VREF, achieving full-scale coverage with the 16-bit converter producing approximately 38 µV per LSB step, sufficient for resolving millivolt-level sensor outputs.
Is ADS8328IPWG4 a suitable alternative to ADS8322 for a 2-channel 16-bit acquisition board?
Yes. The ADS8328IPWG4 is pin-compatible and functionally similar to the ADS8322, both offering 16-bit resolution with 2 analog input channels in a TSSOP-16 package. The ADS8328 series improves on linearity to 0.0046% and offers an SPI interface with up to 20 MHz clock rate, enabling faster data readout in systems that need to minimize MCU interface overhead when capturing at 500 kSPS.
