Frequently Asked Questions
What is the conversion time (t) of the ADC08161?
The typical conversion time is 500 ns, with a maximum conversion time of 560 ns in WR-RD Mode.
What types of applications are suitable for this converter?
Suitable applications include mobile telecommunications, hard-disk drives, instrumentation, and high-speed data acquisition systems.
How is the device reset after a conversion?
The INT active low output pin indicates that a conversion is complete; this signal is reset by the rising edge of RD.
What is required for proper ground connection?
The ground pin must be connected to a “clean” ground reference point, and analog ground should use multiple capacitors if not grounded.
