What are the key features of XDS9224RIRHBR?
- Dual simultaneous-sampling 16-bit SAR ADC at 3 MSPS per channel, capturing two signals with zero phase skew for accurate differential and power measurements
- Integrated 4.096 V internal reference and reference buffer eliminating external precision reference ICs and reducing BOM cost
- Enhanced SPI interface supporting up to 80 MHz SCLK for fast data transfer to FPGA or DSP data acquisition hosts
What is XDS9224RIRHBR used for?
The XDS9224R is designed for high-speed test and measurement instruments, power quality analyzers, and motor phase-current sampling systems where two analog signals must be digitized simultaneously without timing skew. Its 16-bit resolution at 3 MSPS and ±4.096 V input range also make it suitable for radar signal digitization front ends, vibration monitoring systems, and precision multi-channel data acquisition cards in industrial automation.

Frequently Asked Questions
How does the simultaneous-sampling architecture of XDS9224RIRHBR benefit motor phase-current measurement?
Simultaneous sampling captures both phase currents at exactly the same instant with zero phase skew, unlike multiplexed ADCs that introduce tens of nanoseconds of timing error between channels. For a 3-phase motor control loop running at 100 kHz, this eliminates cross-coupling errors of up to 2% that occur when channels are sampled sequentially, improving torque estimation accuracy and control stability.
What is the input voltage range of XDS9224RIRHBR, and does it accept bipolar signals directly?
The analog input accepts signals from -4.096 V to +4.096 V (8.192 V peak-to-peak bipolar range) referenced to a 4.096 V internal reference. This allows direct connection to differential amplifiers, current shunts, and bridge transducers producing bipolar outputs without additional signal-conditioning level shifts, simplifying the analog front-end design.
At what sample rate can XDS9224RIRHBR operate on both channels simultaneously, and how does it compare to lower-speed alternatives?
Both channels sample simultaneously at up to 3 MSPS, providing 6 million total samples per second of dual-channel data. Compared to 1 MSPS dual-channel SAR ADCs, the 3 MSPS rate extends the usable signal bandwidth from about 400 kHz to over 1 MHz per channel (Nyquist limit), enabling the same chip to digitize vibration spectra, ultrasound pulses, and high-bandwidth power transients without hardware redesign.
What QFN package does XDS9224RIRHBR use, and how does the 32-pin footprint facilitate PCB layout?
The device uses a 32-pin VQFN package (S-PQCC-N32) with a compact thermal pad. The QFN format places analog inputs and digital SPI signals on opposing sides of the package, allowing a clean PCB partition with analog supply and ground planes on one side and digital traces on the other, reducing ADC noise floor and maintaining 16-bit linearity with under 0.003% integral nonlinearity.
