Frequently Asked Questions

How many channels does PADC3424IRTQT support and what is its resolution?

PADC3424IRTQT supports 4 analog input channels with 12-bit resolution. The analog input voltage range is ±2 V, and the ADC outputs data in offset binary or 2's complement binary coding, making it compatible with standard DSP and FPGA processing pipelines in multi-channel data acquisition systems.

Which industrial applications benefit most from PADC3424IRTQT's simultaneous 4-channel architecture?

Applications requiring phase-coherent multi-channel sampling benefit the most, including 3-phase motor current sensing, multi-axis vibration monitoring, and power quality analysis. In these cases, all 4 channels must be sampled at the same instant to preserve timing relationships between signals, a capability that PADC3424IRTQT provides with its 12-bit simultaneous sampling architecture.

What is the PADC3424IRTQT package and how does it affect PCB layout?

PADC3424IRTQT uses a 56-pin QFN (Quad Flat No-Lead) package with a heat-slug pad on the underside. The QFN body measures approximately 7 mm × 7 mm, requiring fine-pitch PCB footprints with 0.5 mm pin pitch. Thermal vias under the exposed pad help conduct heat to inner power planes for stable operation across the full temperature range.

When would PADC3424IRTQT be preferred over a single-channel 16-bit ADC for a sensor front-end?

PADC3424IRTQT is preferred when 4 sensors must be sampled simultaneously and 12-bit resolution is sufficient. Using a single 16-bit ADC with multiplexing introduces time skew between channels, which is unacceptable in phase-sensitive applications such as resolver demodulation or 3-phase power measurement operating at signal frequencies above 1 kHz.
