Frequently Asked Questions
How accurate is the ADS8345EBE4 across its 8 analog input channels?
The ADS8345EBE4 delivers 16-bit resolution with a maximum linearity error of 0.0092%, ensuring consistent accuracy across all 8 channels. This level of precision is suitable for strain-gauge measurements, thermocouple amplifier outputs, and other sensor signals requiring sub-millivolt discrimination within the ±2.5 V input range.
What is the maximum conversion speed of the ADS8345EBE4 and how does it affect throughput for 8-channel scanning?
Each conversion completes in a maximum of 6.66 µs, yielding approximately 150 kSPS per channel. When scanning all 8 channels sequentially, effective system throughput is around 18.75 kSPS per channel, making the ADS8345EBE4 appropriate for mid-speed industrial sensor polling at update rates up to several kilohertz.
For a precision industrial PCB with tight space constraints, how suitable is the ADS8345EBE4 package?
The ADS8345EBE4 uses a 20-pin QSOP (Quarter Small-Outline Package) with 0.635 mm lead pitch, offering roughly 40% smaller footprint than an equivalent SOIC-20. This compact form factor allows dense multichannel ADC placement on industrial control boards where PCB real estate is limited, while still supporting manual soldering and standard reflow assembly processes.
When should an engineer choose the ADS8345EBE4 over a lower-resolution 12-bit ADC for sensor acquisition?
A 16-bit ADC like the ADS8345EBE4 resolves signals 16 times finer than a 12-bit part—roughly 76 µV steps at full ±2.5 V range versus 1.2 mV for a 12-bit device. Choose the ADS8345EBE4 when measuring low-level bridge sensors, precision RTD outputs, or battery cell differentials where 12-bit quantization noise would mask real signal variation and degrade closed-loop control accuracy.
