Radiation Hardened High Speed,
Monolithic Digital-to-Analog Converter
Intersil’s Satellite Applications FlowTM (SAF) devices are fully
tested and guaranteed to 100kRAD total dose. This QML
Class T device is processed to a standard ﬂow intended to
meet the cost and shorter lead-time needs of large volume
satellite manufacturers, while maintaining a high level of
The HS-565ARH-T is a fast, radiation hardened 12-bit
current output, digital-to-analog converter. The monolithic
chip includes a precision voltage reference, thin-ﬁlm R-2R
ladder, reference control ampliﬁer and twelve high-speed
bipolar current switches.
The Intersil Semiconductor Dielectric Isolation process
provides latch-up free operation while minimizing stray
capacitance and leakage currents, to produce an excellent
combination of speed and accuracy. Also, ground currents
are minimized to produce a low and constant current through
the ground terminal, which reduces error due to code-
dependent ground currents.
HS-565ARH-T die are laser trimmed for a maximum integral
nonlinearity error of ±0.25 LSB at 25oC. In addition, the low
noise buried zener reference is trimmed both for absolute value
and minimum temperature coefficient.
Speciﬁcations for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Speciﬁcations for the HS-565ARH-T

Deﬁnitions of Speciﬁcations
The HS-565ARH-T 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).

Nonlinearity - Nonlinearity of a D/A converter is an
important 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 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.
Gain Drift - The change in full scale analog output over the
speciﬁed temperature range expressed in parts per million of
full scale range per oC (ppm of FSR/oC). Gain error is
measured with respect to 25oC at high (tH) and low (tL)
temperatures. Gain drift is calculated for both high (tL -
25oC) and low ranges (25oC - 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 oC (ppm of FSR/oC). Offset
error is measured with respect to 25oC at high (tH) and low
(tL) temperatures. Offset drift is calculated for both high (tD -
25oC) and low (25oC - tL) ranges by dividing the offset error
by the respective change in temperature. The speciﬁcation
given is the larger of the two, representing worst case drift.
Power Supply Sensitivity
Power Supply Sensitivity is a measure of the change in
gain and offset of the D/A converter resulting from a
change in -15V or +15V supplies. It is specified under DC
conditions and expressed as parts per million of full scale
range per percent of change in power supply (ppm of
Compliance Voltage is the maximum output voltage range
that can be tolerated and still maintain its speciﬁed accuracy.
Compliance Limit implies functional operation only and
makes no claims to accuracy.
A glitch on the output of a D/A converter is a transient spike
resulting from unequal internal ON-OFF switching times.
Worst case glitches usually occur at half scale or the major
carry code transition from 011 . . . 1 to 100 . . . 0 or vice
versa. For example, if turn ON is greater than turn OFF for
011 . . . 1 to 100 . . . 0, an intermediate state of 000 . . . 0
exists, such that, the output momentarily glitches toward
zero output. Matched switching times and fast switching will
reduce glitches considerably.
