Definitions of Specifications

Digital Inputs

The HS-565ARH accepts digital input codes in binary format

and may be user connected for any one of three binary

codes. Straight binary, Two’s Complement (see note below),

or Offset Binary, (See Operating Instructions).

Accuracy

Nonlinearity - Nonlinearity of a D/A converter is an impor-

tant measure of its accuracy. It describes the deviation from

an ideal straight line transfer curve drawn between zero (all

bits OFF) and full scale (all bits ON).

Differential Nonlinearity - For a D/A converter, it is the

difference between the actual output voltage change and the

ideal (1 LSB) voltage change for a one bit change in code. A

Differential Nonlinearity of

±1 LSB or less guarantees

monotonicity; i.e., the output always increases and never

decreases for an increasing input.

Settling Time

Settling time is the time required for the output to settle to

within the specified error band for any input code transition.

It is usually specified for a full scale or major carry transition,

settling to within 0.50 LSB of final value.

Drift

Gain Drift - The change in full scale analog output over the

specified temperature range expressed in parts per million of

respective change in temperature. The specification is the

larger of the two representing worst case drift.

Offset Drift - The change in analog output with all bits OFF

over the specified temperature range expressed in parts per
