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).

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
full scale range per
o
C (ppm of FSR/
o
C). Gain error is
measured with respect to +25
o
C at high (TH) and low (TL)
temperatures. Gain drift is calculated for both high (TH - 25
o
C)
and low ranges (+25
o
C - TL) by dividing the gain error by the
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
million of full scale range per
o
C (ppm of FSR/
o
C). Offset error
is measured with respect to +25
o
C at high (TH) and low (TL)
temperatures. Offset drift is calculated for both high (TH - 25
o
C)
and low (+25
o
C - TL) ranges by dividing the offset error by the

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
