Frequently Asked Questions
What microprocessors can these A/D Converters interface with?
They interface with the COPS family of micro-controllers, PLD’s, microprocessors, DSP’s, or shift registers.
How many channels does the converter support and what is the multiplexer feature?
It features a configurable input multiplexer for 2 channels, enabling single-ended, differential, or pseudo-differential modes.
What are the key power figures for low-power operation?
The typical power dissipation at full resolution is 8.5mW, but it can enter a low power mode of 3.0mW.
Is an external sample/hold circuit required for accurate readings?
No, it includes a track/hold function that allows the analog voltage to be sampled and held when needed.
