Radiation Hardened High Speed, Monolithic
Digital-to-Analog Converter
HS-565BRH, HS-565BEH
Features
The HS-565BRH, HS-565BEH are fast, radiation hardened
12-bit current output, digital-to-analog converters. This part
replaces the HS-565ARH, which is no longer available. The
monolithic chips include a precision voltage reference,
thin-film R-2R ladder, reference control amplifier and twelve
high-speed bipolar current switches.
• Electrically Screened to SMD # 5962-96755
The Intersil 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.
• Very High Speed: Settles to 0.50 LSB in 500ns Max
HS-565BRH, HS-565BEH die are laser trimmed for a
maximum integral nonlinearity error of ±0.25 LSB at +25°C. In
addition, the low noise buried zener reference is trimmed both
for absolute value and minimum temperature coefficient.
• ±0.75 LSB Accuracy Guaranteed Over Temperature
(±0.125 LSB Typical at +25°C)

Accuracy
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.

Power Supply Sensitivity
No Trim Operation
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 FSR/%).
The HS-565BRH, HS-565BEH will perform as specified without
calibration adjustments. To operate without calibration,
substitute 50Ω resistors for the 100Ω trimming
potentiometers: In Figure 2 replace R2 with 50Ω; also remove
the network on pin 8 and connect 50Ω to ground. For bipolar
operation in Figure 3, replace R3 and R4 with 50Ω resistors.
Typical unipolar zero will be ±0.50 LSB plus the op amp offset.
Compliance
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.
The feedback capacitor C must be selected to minimize settling
time.

Glitch
REF OUT
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.

Calibration
Calibration provides the maximum accuracy from a converter by
adjusting its gain and offset errors to zero. For the HS-565BRH,
HS-565BEH, these adjustments are similar whether the current
output is used, or whether an external op amp is added to
convert this current to a voltage. Refer to Table 1 for the voltage
output case, along with Figure 2 or 3.
Calibration is a two step process for each of the five output
ranges shown in Table 1. First adjust the negative full scale (zero
for unipolar ranges). This is an offset adjust which translates the
output characteristic, i.e., affects each code by the same
amount.
Next adjust positive FS. This is a gain error adjustment, which
rotates the output characteristic about the negative FS value.
For the bipolar ranges, this approach leaves an error at the zero
code, whose maximum values is the same as for integral
nonlinearity error. In general, only two values of output may be
calibrated exactly; all others must tolerate some error. Choosing
the extreme end points (plus and minus full scale) minimizes this
distributed error for all other codes.

HS-565BRH, HS-565BEH
Settling Time
This is a challenging measurement, in which the result depends
on the method chosen, the precision and quality of test
equipment and the operating configuration of the DAC (test
conditions). As a result, the different techniques in use by
converter manufacturers can lead to consistently different
results. An engineer should understand the advantage and
limitations of a given test method before using the specified
settling time as a basis for design.
The approach used for several years at Intersil calls for a strobed
comparator to sense final perturbations of the DAC output
waveform. This gives the LSB a reasonable magnitude (814mV)
for the HS-565BRH, HS-565BEH, which provides the comparator
with enough overdrive to establish an accurate ±0.50 LSB
window about the final settled value. Also, the required test
conditions simulate the DACs environment for a common
application - use in a successive approximation A/D converter.
Considerable experience has shown this to be a reliable and
repeatable way to measure settling time.
The usual specification is based on a 10V step, produced by
simultaneously switching all bits from off-to-on (tON) or on-to-off
(tOFF). The slower of the two cases is specified, as measured
from 50% of the digital input transition to the final entry within a
window of ±0.50 LSB about the settled value. Four
measurements characterize a given type of DAC:
(a)
tON, to final value +0.50 LSB
(b)
tON, to final value -0.50 LSB
(c)
tOFF, to final value +0.50 LSB
(d)
OFF, to final value -0.50 LSB
(Cases (b) and (c) may be eliminated unless the overshoot
exceeds 0.50 LSB). For example, refer to Figures 4A and 4B for
the measurement of case (d).
Procedure
As shown in Figure 4B, settling time equals tX plus the
comparator delay (tD = 15ns). To measure tX,
• Adjust the delay on generator number 2 for a tX of several
microseconds. This assures that the DAC output has settled to
its final wave.
• Switch on the LSB (+5V)
• Adjust the VLSB supply for 50% triggering at COMPARATOR
OUT. This is indicated by traces of equal brightness on the
oscilloscope display as shown in Figure 4B. Note DVM reading.
• Switch to LSB to Pulse (P)
• Readjust the VLSB supply for 50% triggering as before, and
note DVM reading. One LSB equals one tenth the difference in
the DVM readings noted above.
• Adjust the VLSB supply to reduce the DVM reading by 5 LSBs
(DVM reads 10X, so this sets the comparator to sense the final
settled value minus 0.50 LSB). Comparator output disappears.
• Reduce generator number 2 delay until comparator output
reappears, and adjust for “equal brightness”.
• Measure tX from scope as shown in Figure 4B. Settling time
equals tX + tD, i.e., tX + 15ns.

Other Considerations
Grounds
Layout
The HS-565BRH, HS-565BEH has two ground terminals, pin 5 (REF
GND) and pin 12 (PWR GND). These should not be tied together
near the package unless that point is also the system signal
ground to which all returns are connected. (If such a point exists,
then separate paths are required to pins 5 and 12).
Connections to pin 9 (IOUT) on the HS-565BRH, HS-565BEH are
most critical for high speed performance. Output capacitance of
the DAC is only 20pF, so a small change of additional capacitance
may alter the op amp’s stability and affect settling time.
Connections to pin 9 should be short and few. Component leads
should be short on the side connecting to pin 9 (as for feedback
capacitor C). See the “Settling Time” section on page 5.
The current through pin 5 is near zero DC (Note); but pin 12
carries up to 1.75mA of code - dependent current from bits 1, 2,
and 3. The general rule is to connect pin 5 directly to the system
“quiet” point, usually called signal or analog ground. Connect pin
12 to the local digital or power ground. Then, of course, a single
path must connect the analog/signal and digital/power grounds.
NOTE: Current cancellation is a two step process within the
HS-565BRH, HS-565BEH in which code dependent variations
are eliminated, the resulting DC current is supplied internally.
First an auxiliary 9-bit R-2R ladder is driven by the complement
of the DACs input code. Together, the main and auxiliary
ladders draw a continuous 2.25mA from the internal ground
node, regardless of input code. Part of the DC current is
supplied by the zener voltage reference, and the remainder is
sourced from the positive supply via a current mirror which is
laser trimmed for zero current through the external terminal
(pin 5).
6
Bypass Capacitors
Power supply bypass capacitors on the op amp will serve the
HS-565BRH, HS-565BEH also. If no op amp is used, a 0.01µF
ceramic capacitor from each supply terminal to pin 12 is
sufficient, since supply current variations are small.

NOTES:
1. Index area: A notch or a pin one identification mark shall be located adjacent to pin one and shall be located within the shaded area shown.
The manufacturer’s identification shall not be used as a pin one identification mark. Alternately, a tab (dimension k) may be used to identify
pin one.
2. If a pin one identification mark is used in addition to a tab, the limits of
dimension k do not apply.
3. This dimension allows for off-center lid, meniscus, and glass overrun.
4. Dimensions b1 and c1 apply to lead base metal only. Dimension M applies to lead plating and finish thickness. The maximum limits of lead
dimensions b and c or M shall be measured at the centroid of the finished lead surfaces, when solder dip or tin plate lead finish is applied.
5. N is the maximum number of terminal positions.
6. Measure dimension S1 at all four corners.
7. For bottom-brazed lead packages, no organic or polymeric materials
shall be molded to the bottom of the package to cover the leads.
8. Dimension Q shall be measured at the point of exit (beyond the meniscus) of the lead from the body. Dimension Q minimum shall be reduced
by 0.0015 inch (0.038mm) maximum when solder dip lead finish is
applied.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH.
