All 8 channels are sampled simultaneously at 200kSPS, preserving the phase relationships critical for power quality analysis and multi-axis vibration measurement. The true bipolar input range of +\/-10V or +\/-5V is software-selectable, eliminating the need for external signal conditioning for typical industrial voltage ranges. The +\/-16.5V overvoltage protection on all inputs provides robustness in harsh industrial environments. The device supports both parallel and SPI interfaces for flexible connectivity to various host processors. An internal 2.5V reference simplifies design, while the on-chip oversampling digital filter improves SNR for applications requiring higher precision.","working_principle":"The AD7609 uses a successive approximation ADC architecture with 8 independent track-and-hold amplifiers that sample all channels simultaneously on the CONVST rising edge. Each channel has its own analog input buffer, track-and-hold, and SAR ADC. The converted data is stored in channel data registers. The parallel interface provides fast data readback (18-bit bus), while the SPI interface reduces pin count for processor-constrained designs. The input range is selected via the RANGE pin or software register. In +\/-10V mode, the input attenuator scales the signal for the internal 5V ADC range. In +\/-5V mode, the attenuator is bypassed for improved SNR. The hardware oversampling mode accumulates and averages multiple conversion results internally, improving effective resolution by up to 3 bits at 64x oversampling while reducing throughput proportionally.","pin_description":"
