What are the key features of ADS8329IPWR?
- 16-bit resolution at 1 MSPS throughput with 0.786 µs conversion time enabling precise high-speed data acquisition across the full audio and industrial sensor bandwidth
- Ultra-low 0.0038% linearity error (approximately ±2.5 LSB INL at 16 bits) ensuring measurement accuracy comparable to bench instrumentation in a small IC
- 2.7 V to 5.5 V wide supply range with SPI-compatible serial interface simplifying direct connection to 3.3 V and 5 V microcontrollers without external level shifting
What is ADS8329IPWR used for?
ADS8329IPWR is used in industrial data acquisition systems, vibration monitoring equipment, and medical instruments that require 16-bit resolution at 1 MSPS to capture fast-changing analog signals with high fidelity. Its low linearity error of 0.0038% makes it suitable for precision current measurement front ends in energy meters and motor controllers where ADC nonlinearity directly translates to power calculation error. Scientific instruments including spectrum analyzers and lock-in amplifiers also use ADS8329IPWR for its combination of high dynamic range, fast throughput, and compact 16-pin TSSOP footprint.

Frequently Asked Questions
What is the maximum throughput rate and conversion time of ADS8329IPWR?
ADS8329IPWR achieves 1 MSPS maximum throughput with a 0.786 µs conversion time per sample. This speed supports digitizing signals with bandwidth up to 500 kHz in accordance with the Nyquist criterion, covering vibration sensor frequencies up to 20 kHz with 25× oversampling for digital filter processing or direct sampling of audio-band signals up to 48 kHz at 20× oversampling.
How does the 16-bit resolution of ADS8329IPWR translate to measurement accuracy in a 5 V input range system?
With 16-bit resolution over a 5 V analog input range, ADS8329IPWR has a 1 LSB step of approximately 76 µV. Its 0.0038% linearity error corresponds to about ±2.5 LSB of integral nonlinearity, giving a measurement accuracy of approximately ±190 µV referenced to input. This level of precision is sufficient for 4-20 mA industrial transmitter digitization, thermocouple measurement with cold-junction compensation, and bridge-sensor weighing applications.
What supply voltage range does ADS8329IPWR accept and how does it interface with a 3.3 V microcontroller SPI bus?
ADS8329IPWR operates from 2.7 V to 5.5 V VDD and its digital I/O logic thresholds scale with supply, so at 3.3 V supply the SPI pins are directly compatible with 3.3 V MCU GPIO without level shifters. At 5 V supply, a 3.3 V MCU may need series resistors or a level translator on MOSI and CS lines to avoid exceeding the 3.6 V input clamp, while MISO output can be read directly at 3.3 V logic threshold.
For a vibration monitoring system sampling at 500 kHz, how many ADS8329IPWR channels are needed for a 3-axis accelerometer?
ADS8329IPWR is a single-channel ADC, so a 3-axis accelerometer system requires 3 separate ADS8329IPWR devices to sample all 3 axes simultaneously at 500 kHz each. If sequential sampling is acceptable, 1 device multiplexed through a 4-channel analog switch can cycle through 3 axes at 333 kHz per axis, capturing vibration frequencies up to 166 kHz per axis with the signal bandwidth remaining above typical 100 kHz accelerometer response limits.
