Frequently Asked Questions
What is the resolution and sampling rate of the ADS8694?
The ADS8694 provides 18-bit resolution with a maximum throughput rate of 500kSPS (kilo-samples per second). This combination enables precise, high-speed digitization of analog signals across its 4 input channels.
What input voltage ranges does the ADS8694 support?
The ADS8694 supports programmable bipolar and unipolar input ranges including ±10.24V, ±5.12V, ±2.56V, ±1.28V, and 0V to 10.24V. These selectable ranges provide flexibility for diverse sensor and signal conditioning applications without external level shifting.
How many channels does the ADS8694 have and what is the supply voltage?
The ADS8694 has 4 fully differential input channels with an auto-scan feature for sequential conversion. It operates from a single 5V supply, simplifying power design and reducing the need for additional power rail generation.
What package is the ADS8694 available in?
The ADS8694 is available in a small outline package (TSSOP or similar compact SMD package). The small form factor makes it suitable for space-constrained designs in industrial and measurement equipment where PCB area is at a premium.
What types of applications is the ADS8694 most suitable for?
The ADS8694 excels in industrial data acquisition, process control, power quality monitoring, motor drive feedback, and scientific instrumentation. Its 18-bit resolution, bipolar input ranges, and 500kSPS speed make it a strong fit for any application needing accurate multi-channel analog measurement.
