A/D Converter Selection Table

From the table below, select the combination of Sampling Rate and bit width required for the A/D(s). Click on "Avail" for the choice of AED models that can provide the selected capability. ? indicates the category has not been researched and documented. Please complete a Customer Reply Form indicating A/D, D/A and interface requirements. We will search for devices that meet your needs that fit on an AED product.

In feedback control applications, latency is often the critical specification instead of sample rate. In order to get the desired latency, A/D converters with higher sample clock rates may be used to reduce the latency while only some of the samples that the converter produces may be collected. A special option is available for this purpose. Selection of the highest sample rate for the bit width available in the table below will generally show the lowest latencies available. Parallel interface converters will have lower latency that serial device interfaces.

A/D Sample Rate	8-bit	10-bit	12-bit	14-bit	16-bit	18-bit	20-bit	22-bit	24-bit
Up to 100 KS/s				Avail	Avail	?	?	?	Avail
100+ to 200 KS/s			Avail	Avail	Avail	?
200+ KS/s to 1 MS/s			Avail	?	Avail
1+ to 10 MS/s	Avail	Avail	Avail	?
Above 10 MS/s	Avail	Avail	Avail	?

Table Notes:
KS/s - Thousands of Samples per Second
MS/s - Millions of Samples per Second
