Applications
The ADC128S102WGRQV is designed for satellite power management systems, spacecraft attitude control sensors, and avionics data acquisition units requiring radiation-tolerant 12-bit analog digitization across 8 channels at up to 1 MSPS. Its radiation hardness and wide analog input range of up to 5.25 V make it suitable for monitoring solar array currents, battery voltages, and thermal sensors in orbital environments. Defense electronics systems such as radar signal processors and UAV telemetry boards also deploy this device where guaranteed performance under ionizing radiation is mandatory.

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.
