Frequently Asked Questions
What sampling rate range does the ADC128S102WGRQV support and how does it scan 8 channels simultaneously?
The ADC128S102WGRQV operates at throughput rates from 50 kSPS to 1 MSPS with a maximum conversion time of 0.8125 µs per sample. It sequentially scans up to 8 analog input channels under SPI command control, enabling an effective per-channel update rate of 125 kSPS when all 8 channels are scanned at full 1 MSPS aggregate throughput.
Why is the ADC128S102WGRQV specified for radiation-hardened applications and what environments is it designed for?
The device is radiation-hardened to withstand total ionizing dose (TID) levels required in low-earth orbit and geosynchronous orbit satellites, where accumulated radiation can corrupt standard CMOS circuits within months. Texas Instruments qualifies this part for space applications where bit errors and latch-up from heavy ion strikes would cause mission failure in a standard 12-bit ADC operating at 1 MSPS.
How does the 0.027% maximum linearity error of the ADC128S102WGRQV affect measurement precision in a 12-bit system?
A maximum linearity error of 0.027% corresponds to approximately 1.1 LSBs at 12-bit resolution (4096 counts), meaning the device maintains differential nonlinearity well within ±1 LSB across its full analog input range of 0 V to 5.25 V. This precision is essential in spacecraft power monitoring where a 1 LSB error at full scale represents roughly 1.3 mV at 5 V reference, affecting battery state-of-charge calculations.
How does the 16-pin SOIC package of the ADC128S102WGRQV compare to competing radiation-hardened ADCs for board layout constraints?
The CDSOIC-16 package (JESD-30 R-CDSO-G16) has a body width of approximately 3.9 mm with 1.27 mm pin pitch, offering a compact footprint for space-grade PCBs where mass and volume are tightly budgeted. Compared to ceramic DIP or flatpack alternatives common in military-grade ADCs, the surface-mount SOIC reduces PCB drilling and allows placement on both sides of the board, cutting assembly cost for programs that need 12-bit multi-channel ADCs in radiation environments.
