Frequently Asked Questions
How many input channels does the ADS8345NG4 have and what is its resolution?
The ADS8345NG4 features 8 analog input channels with 16-bit resolution. This combination allows a single IC to replace multiple lower-channel ADCs in multi-sensor systems, simplifying board design and reducing component count while maintaining high measurement precision.
What is the conversion time and linearity error of the ADS8345NG4?
The ADS8345NG4 has a maximum conversion time of 6.66 µs and a maximum linearity error of 0.0122%. These specifications make it suitable for precision measurement applications requiring both fast throughput and high linearity across the full ±2.5V analog input range.
What analog input voltage range does the ADS8345NG4 support?
The ADS8345NG4 supports a bipolar analog input voltage range of -2.5V to +2.5V. This bipolar range allows direct connection to differential sensor outputs and signal conditioning circuits that produce both positive and negative output voltages without requiring additional level shifting.
What converter type and package does the ADS8345NG4 use?
The ADS8345NG4 uses a successive approximation register (SAR) ADC architecture, which provides a good balance of speed, resolution, and low power consumption. It is housed in a 20-pin SSOP (Shrink Small Outline Package), offering a compact footprint with standard pitch lead spacing for easy PCB assembly.
