TERMINOLOGY

Integral Nonlinearity (INL)

This is the single most important DAC specification. Analog

Devices, Inc., measures INL as the maximum deviation of

the analog output (from the ideal) from a straight line drawn

between the end points. It is expressed as a percent of full-scale

range or in terms of LSBs.

Refer to the Analog Devices Glossary of EE Terms for

additional digital-to-analog converter definitions.

Interface Logic Information

The DAC8043 has been designed for ease of operation. The

timing diagram (see Figure 12) illustrates the input register

loading sequence. Note that the most significant bit (MSB)

is loaded first.

Once the input register is full, the data is transferred to the

DAC register by taking LD momentarily low.
